    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.

    Cheers mate, just had this confirmed by them on the phone. They will also offer me a military discount so that’s a bonus.

    James, did you run your car at Santa pod this weekend?

    Bit of a late reply, no haven't been santapod yet. Was due to go tomorrow but looks like it's going to be 7th July now!

    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

    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!
