    Had the car tuned at MRC this week, mods include scorpion turbo back with decat, forge intercooler and k&n filter.

    The car made 501PS and 660nm.

    Results show good gains all round, although peak figures before and after aren't as high as some.

    The car feels much faster, it's now voilently fast and is much more fun to drive! Throttle response is also improved and the gearbox reacts quicker and just feels better all round. I did notice that sometimes after doing a launch that the 1st > 2nd gear change can feel a bit brutal and sometimes hear a loud clunk from what must be the gearbox? If anyone else has this please let me know. Overall the power delivery is great and the car drives as standard under normal driving.

    Went out to test times with dragy, pretty happy with the results considering it's been very warm and humid, around 24 degrees when I did these runs (my stock runs were done around 10 deg c).

    Breakdown stock vs tuned:
    0-60 mph: 3.56 / 3.07
    0-100 mph: 8.47 / 6.95
    1/8 mile: 7.51 @ 93.31 / 7.03 @ 100.93 mph
    1/4 mile: 11.87 @ 115.75 / 10.95 @ 124.64 mph
    100-200 kph: 10.16 / 7.51
    0-200 kph: 14.04 / 10.88

    10 sec car on pump gas. I assume on 98Ron.

    That's just brilliant

    This platform is just unreal. Soo much potential.

    Great improvements over the stock time, considering you haven’t even upgraded the stock intake.

    No need to upgrade the stock intake.

    The big turbo 700-800hp 9sec cars haven’t so there’s no requirement for a 500hp car. Panel filter and possibly a larger turbo intake pipe to allow better flow possibly and James has already got the less restrictive K&N in there.

    Nice results James, the winter mid acceleration times will be even better as will the dyno figures. Great gains from the before vs the after.

    The pic of the dyno chart is grainy and I can't see the numbers. Can you post a clearer pic. Would love to compare the gains against my old PFL RS3 from MRC!

    As said, great results and a bonkers fast car now!

    I haven't cross checked but first glance it looks like the big gains over the PFL remap are higher up the rev range. In the PFL the biggest gains were seen at 4000rpm or so. This seems more like 5000rpm. @Beebee-one you're a good guide on this with lots of data. Thoughts?

    Doc, here's the dyno chart for my stage 1 and stage 2 MRC remaps for my PFL car which was done just over a year ago. Stage 2 was with Forge IC and K&N air high flow filter only - no downpipe. Stage 2 peak numbers were 451ps and around 689nm torque. MRC have now developed their PFL stage 2 maps even further and there are now cars getting 460ps and over 700nm on the stock turbo.
    The interesting part is the FL car holds it's torque across a wider rev range (some I have seen actually show it to continue to increase up to 5K rpm) but the PFL car seems to pick up slightly earlier - probably a characteristic of the smaller turbo spooling up quicker on the PFL car. The smaller turbo of the PFL car begins to run out of puff at the higher rpm, whereas the FL car's larger turbo starts to get into it's stride past 4k rpm and power is still building right up to 6500rpm before tailing away.
    I now have the FL car and can feel how the power on the stock engine really starts to pull at the higher rpm. My FL car is fast but lacks the big slug of low down torque that my stage 2 car had in abundance. I plan to have the MRC stage 2 custom tune (but no downpipe) sometime in July and will report back as to how it works out. I am only expecting to see around 480ps and 650nm without the downpipe but will consider adding one when there are a few more options available other than the usual Milltek offering. I also have one or two other things that I may be adding too but will reveal what these are when they have been tested.

    Great results and great information as this is my next step for my FL RS3. Out of curiosity how much coin did MRC charge for the pleasure?

    MRC I think charge £750 inc vat for a stage 1 and a little more for stage 2 maps.

    Monopole and I are planning to be at SP on the 7th July so maybe see you there?
    Both cars are going on the dyno this weekend to establish stock numbers, we are also adding the HG Motorsport intake to see what it does on a stock engine. The following week we will be having both cars tuned at MRC (mine will have the Forge IC added) and then run them at SP on the 7th. I will then decide if I want to add a downpipe but haven't made my mind up on which one yet. Probably gonna go for a sports cat version (Milltek do one with a 200 cell cat) so will be interesting to see what these parts add in isolation. Other mods to be added in the subsequent months during the summer.

    Careful with the pops and bangs map if you are going for a catted Downpipe.

    Both APR and Revo have warned against them on a Stage 1 due to quick degradation of the cat. APR have actually stated that stock tuned cars are likely to suffer from cat damage.

    If you go Stage 2 and get the pops and bangs map added with a Sports cat, chances are you’ll probably fail that MOT at 3yrs. I don’t think the Sports cat will protect against the ‘wastegate’ rattle either.

    It appears the only safe way of having a pops and bangs map is to have a decat, no cat to damage.

    You could just opt out of the Pops and bangs map in the Stage 1 and 2 if you’re going to have a cat in there, or you could just ignore and pay no attention to APR and revo’s advice.

    Car definitely needs a cooler for sure.

    Do you have a K&N / Pipercross panel filter to put in the box for the HG intake pipe?

    I have got used to my FL car now and the lack of pops n bangs does not really bother me anymore. Been there and done that with the PFL car, had stage 2 with static rev limit removed DSG reprogrammed and it sounded like a 1980's rally quattro when launched. However, I am quite happy with the sound from my FL car with the backbox valves disconnected (at the moment at least)

    Monopole (Steve) and I are deliberately tuning our FL cars in incremental stages so that we can find out what you can expect from the parts that are bolted on. Steve's car will be equivalent to a stage 1 with just software upgrade by MRC. These engines run hot when pushing over 480ps so I will be adding a Forge FMINT 4 intercooler and MRC will be doing a custom map - I hope to see somewhere north of 480ps but not expecting to be over 500 without a downpipe which I may opt to fit at a later date. Both cars have air filter upgrades, K&N on mine and a BMC on Steve's car. The final numbers will depend on the starting power baseline for the stock engines.

    In addition to the above, I have also been looking at larger intakes and the HG Motorsport intake has been lined up to see how it performs. No plans to change the airbox as the OEM unit is fine for power levels at this stage.
    We plan to run both modified FL cars at SP on the 7th July to see how they compare to the times for our stage 2 PFL cars that we ran on numerous occasions at SP last year.

    HG Motorsport intake is nice and large compared to the OEM part
    IMG_3407.JPG
    However, anyone considering fitting one of these should be aware that the support bracket on the pipe is not welded in the correct position and needs to be manipulated (bent and spacer added) to fit correctly. Other than that, it's not bad for just 209 Euro's!

    Agree about the HG pipe.

    Bracket is a good 15mm from where it should be....

    [​IMG]

    However a little modification and a spacer allows the Torx bolt to be put back in thus securing it as OEM.

    As Beebee says for 200 odd Euros it’s a good buy.

    For SRR run tomorrow, mine will not have the high flow air filter (not yet arrived) (and it is also K&N as the company supplying the BMC don't have stock - ordered 3 weeks ago and they only admitted this on Wednesday when I raised a complaint through ebay), so will be interesting to see "stock" vs beebee-one's filter, then filter+HG intake pipe.

    I plan to have just ecu stg1 as I don't want to go to the expense like I did with my PFL with modifications, but SP on the 7th will give me an idea, as I said before, I have my own goal of beating my PFL 11.69s at 117mph and not looking for the quickest/fastest rs3 with headline hp. I'm looking forward to MRC on the 3rd and hope for 470+ and 600nm+.

    Interesting thread, although I don't think its the best time of year to be reaching for the stars figures wise. I'd even opt for mapping a car at a completely different time of year given the temperatures we're expecting over the next couple of weeks. I guess its all still relative though.

    Where have you mounted it?

    Put it on the dash under the windscreen. If you mount it low down it has problems locking on to satellites. First time I used it I had it under the heating controls, locked onto one and the 2nd was intermittent. Done a few runs and thought it was broke , 0-60’s coming back at 5-6secs and invalid messages showing. Mounted it higher up so both satellites locked and all was good.

    Also, delete BT device and find it again on phone.

    trip up to Surrey Rolling Road today with Bri (beebee-one), interesting results for a stock car;

    currently on just under 1500 miles and mine returned 422.8 bhp and approx ~400 lbsft (~540Nm that I can work out from the graph), make of that what you will, bare in mind, my PFL tested 438 bhp with MRC and 440 bhp at SRR.

    good to see TX also in his beast of an RS4, I'm sure Jon and Bri will post their results at some point - Bri also has an overlay of mine and his car (and some discussion points)

    Was your PFL stock when it returned 438bhp and 440bhp? If so, that's incredible.

    Forgetting the dyno numbers for a moment, how to you do the cars compare in a straight line? I couldn't tell a jot of difference. Although I appreciate when we're down to tenths of a second that you can't really tell much.

    Following up on Steve's (Monopole) post above, the dyno session at SRR this morning was 'interesting' but also a little frustrating for several reasons which I will mention shortly. So the objective was to run both FL cars, one as completely stock, the other also stock and then with the HG intake and K&N filter to see the difference it makes without any software adjustments. The results can be seen below on the dyno chart, Steve's stock car is the GREEN plot line and my car with the HG intake pipe and K&N is the RED line. For clarity, the more squiggly lines at the lower half of the graph are the air fuel ratios (AFR's) plotted across the rev range. The smoother lines at the top part of the chart are the power outputs measured for each car.

    Before I get into the graph results I just want to mention the utter balls up with the OEM and also the HG intakes. I checked my OEM intake last night and discovered that it had come loose at the turbo elbow joint which is secured with a spring clamp over a hard plastic shroud. I had removed it the day before to prepare everything for a quick changeover at the dyno when swapping it with the HG intake. What I discovered was the plastic shroud had shrunk slightly when it cooled after being removed. Re-fitting it in a secure position was near damn impossible as it no longer aligned properly. This left me with no option but to fit the HG intake which I subsequently discovered as also having some serious issues with alignment between the airbox and turbo inlet elbow. I managed to get it on the car but it definitely needs HG to refine the fitment.

    Right, back to the dyno results.....Please note that I don't want to get into a discussion around dyno accuracy, this was done purely as an experiment to see what we would get as an 'apples for apples' comparison for tuning hardware done on the same equipment, same day.
    Steve's car went on first and ran a very respectable 422.8bhp and good torque at just over 400lbs/ft. He said it felt fast compared to his PFL car and seems to have been proven right.
    Next up was my car with the HG intake pipe with K&N filter fitted. As you can see from the dyno plot (the RED line) it started off very well with some significant gains at the lower rev range (it looks small but check out the scale of the graph axis on the left - maybe 15+bhp over stock at 3K rpm?) and smooth power delivery right up to over 5000rpm. However, its at this point where you can see the air fuel ratio (AFR) shows the engine beginning to run lean and the ECU consequently reigning in the power to protect the engine. It still made 415bhp and a nice peak torque at 420lbs/ft (separate graph).

    So...... it appears that the larger intake adds more power/torque by flowing more air to the engine, but it will need a proper mapping session to take full advantage of the extra air being supplied and adjust fueling etc to get the engine to run properly at the higher rev range. Out on the road my car feels fast but I cannot feel the ECU pulling the power at 5k rpm. This is a good example of where randomly bolting upgrade bits on to your car without optimising how they work can cause problems.
    I will be having the OEM intake refitted this week and will dyno it as stock next weekend just to be sure everything it ok before it goes to MRC the following week.

    So the stock car was Dyno with more power than your modded car!?

    I wouldn’t trust any thing that dyno says if it has such large inconsistencies.

    Interestingly enough the APR tune shows the stock RS3 at 420HP.

    Well done lads. Really interesting read and will look forward to reading the future developments. Seems like consistently much more torque being developed from these engines than Audi claim.

    Errrrrm........have you actually read the post properly? The modded car made more power than the stock car at lower rpm, but then the car with the air intake mods began to run too lean and the ECU intervened. Nothing to do with the dyno being inconsistent.

    Sorry I missed this but then that concerns me that the car would be modded and not be able to handle the extra power for whatever reason (be it not enough air or whatever) seems like someone is blagging it and doesn’t know what they are doing.
