    Gents,

    After much deliberation I finally chose my new car, an Audi A4 S Line (211ps) B8 model (2009-10)
    I am now reviewing the immediate modifications to apply, and seeking some advice before progressing.

    1, alloys will be replaced with the 19" 7 Arm Dual spoke alloys wrapped in some Perrilli P Zero Nero's (a tyre i have now used on all my previous cars) I have seen a few people painting their brake calipers, however I was planning on have the stock parts replaced for Brembo calipers/brakes and disks. - has any one done this already and do you find any improvement above and beyond the stock units

    2, I want to replace the front grill with the RS4 honeycomb grill - is this a direct replacement or is further modification required for this unit to fit?

    3, I want to replace the exhaust system with a miltek system - fitted by AMD technik Essex replacing the rear valance with the S4 dual pipe version. Has anyone experience of the miltek system? and in regards to replacing the valance, is this a simply pop off and on or requires further modification?

    4, I want to replace the windows with tinted windows, I have no exerpience of film tinting, however have seen many done badly which leads me to ask does anyone do replacement tinted OEM glass? and how much would I expect to spend on replacing all the glass?

    5, I have done much reading on the replacement of the cold air intake filter, with a K&N panel filter - obviously taking into consideration that the unit should be washed and dried before using for the first time to avoid the factory oil residue. I understand there is next to no HP increase with this but smooths out the acceleration and makes it abit throatier? Again - has anyone installed one? Good/ Bad/ Indifferent about them?

    6, I finally want to remap the ECU, I assume its best todo this once exhause system, panel filter and new alloys are replaced. Does anyone have any advice on which one would be best to go for - again i intend to drop it into AMD Technik to install the Revo. Has anyone had this installed - again Good / Bad Indifferent?

    ---

    This is my modification schedule, is there any other quick wins for performance and handling that im missing?

    Thanks in advanced

    Regards,
    Robert

    Hi,
    I bought an S4 saloon from Audi Reading. It is not an option to have privacy glass on the saloons, but audi Reading did them in their workshop for around £220. they look great- you wouldn't know that it hadn't been done at the factory. The ONLY thing I have noticed, that I didn't consider was that the interior mirror obviously won't auto dim, beacause there is never enough light to cause it to, and this means you can never turn off the dimmer to see whether it's a police car behind you at night.
    With regards to the remap, I went to QS Tuning, an Audi specialist, who fitted an MTM box, also made by Audi specialists, which increased the power to 430 BHP and torque by 100Nm. It's a bolt on part, which can be easily removed if the car needs to go in for warranty work etc.

    I had my b8 2.0 Tfsi 211 Bhp Manual Remapped by Revo Technik, Simply the best thing i have ever done, the power output is much more smoother the difference in performance is just unbelievably amazing and the Fuel Consumption goes up alot more.
    Mine was Remapped to 305 Bhp as from factory standard it has a vvl (Variable valve lift) engine which can take all the power without any damage or strain, if you phone up Revo Headquarters in Northampton they will give you much more information on this.
    When they Remap it they undo the bolts on the Ecu (Engine Control Unit) under the bonnet and pull the Ecu out and attach it to there machine which links through to Revo and downloads the Software onto it, this process takes a few hours to complete but is well worth it, it is then put back where it belongs and the bolts are replaced so that Audi Cannot tell that it has been tampered with,Audi can also not trace the Remap on there System,
    Having it Remapped also make the exhaust sound a little more Throatier.
    What year is your car ? because you might also want to check out the Software update on your car, because if you get the remap and then you take your car back to Audi they will give it a Software Update to the computer which will overide the Remap so you will have to go and pay an extra £65 to go and get the Remap re installed again.
    Make sure you use Shell V Power Fuel in your car whether it is Remapped or not because i have had problems using the terrible quality Tesco 99 Momentum.
    All the Modifications you are planning on doing sound very good, after its done make sure you upload some photos !
    If you have any more Questions about the Remap then please ask because i have experience on the Remap you are planning.

    Hi there - I am new to this forum, I also have a brand new A4 2.0TFSI. You say that Revo mapped your car to 305 BHP, is that a stage one or two remap? I would personally be worried to have that much power increase without engine modifications. Most stage 1 remaps quote around +50BHP max. I have done quite a bit of investigation around remaps and the conclusion for me is not so much around BHP gains, more around how it will drive and put the power down. Something with a smooth power delivery I would imagine would be better for the engine. Audi dynamik - how would you describe the power delivery?

    Audi dynamik - have you had your car dyno'd since it was remapped? I'd expect about 250 out of a stage 1 on that engine, I've got around 300 out of my stage 1 with a bigger turbo and intercooler. Sounds a bit like your tuner was making some false claims there

    Yeh its perfectly safe, it can be done with the 211 bhp a5 and a4 due to the vvl , i have had my remap since i have had the car and never had one problem the car is just some much better.
    If you go the this link and find your engine it will tell you the performance.
    http://www.revotechnik.com/resources/uploads/files/VAG App List UK __ 301111.pdf
    I have spoke to the Revo Manager myself and it is actually a stage 1 Remap and it will not do any harm to the engine what so ever no other modifications are needed to stand the power, Revo are one of the Biggest and the Best tuning companies out there across the World and they know right.
    The Power output is much more smoother than it were before, hard to explain but there is a difference.
    I havent yet had it dynoed, but there was a big fuss when a car exactly like mine first went to Revo and got all the Power out of a stage 1 with out any damage to the engine, it was dynoed when it was done and there is a photograph for proof somewhere on the website or facebook page showing the actually 305 Bhp the claimed was true.
    Many Tuning Companies will only put it to about 245-250 because they are afraid of any problems occurring if they go higher which is not the case because the VVL engine is responsive to tuning and the remap will not strain the engine which most tuning companies are un aware of.
    Ive also raced a stock Audi s3 and won if this is any help ? :p

    Fair enough, in your situation I'd have gone with revo too with those sort of gains from a stage 1! :eek:

    I wouldn't be claiming your car has 305bhp until you have had YOUR car on a dyno, all cars are different!

    appleton - Your planned mods seem pretty good. For the grille though I think it's the RS5 grille you'll need, the B8 RS4 has just been launched but has a facelift grille so won't fit a 2009-10 car. Are you planning on doing anything to the suspension?

    Im not claiming it as at 305 Bhp for certain, But that it was Revo says and i know its somewhere around there.

    Appleton,

    The proper way of choosing a map is to find out how the maps been done i.e. word of mouth, test drives or graphs.

    Having peoples comments of stuff like "it's really good" doesn't tell you anything if they've not compared it with other remaps. On a previous car I tried 4 maps before I chose the one I wanted. One of them I hated (felt fast but was all surge and really small power band), one I didn't like, one was ok and one I loved.

    Revo claims are dismissed by many on forums in the UK and US on the basis they appear too good to be true and they make vastly different claims to other professional tuners. Various requests have been made for independant dynos but the owners never produce.

    If the figures are correct then you have to consider the power delivery. Also the power must come from somewhere so the suspicion is massive boost. Sensible tuning won't cause "damage" but it will increase wear etc. If you've bough new then it's unlikely you'll still have the car by the time this becomes an issue but it's something to consider.

    Finally anyone who suggests Audi won't be able to detect it are either lieing or misinformed.

    I beg to differ my man. Whoever told you that a remap is invisible needs to take themeselves away and re-educate themselves. There are many tuning companies online who state that their remaps are "undetectable" and this simply isn't true. While it may not be physically apparent it is relatively easy to find out by comparing the contents of the ECU with a standard one, by verifying the checksum (a value calculated against the contents of the ECU), and by taking the vehicle for a test drive and taking some logs of the data provided by the ECU. Remapping is NOT undetectable, and don't let anyone tell you different.

    Imagine your surprise after a remap when you take your car back to the garage (if it needs warranty work) to be told that the warranty is void as its been remapped. And your going to argue with them as your tuner told you in was invisible.......I bet you'd be right royally cheesed off. And in your case I would be planning on getting my engine inspected as a 100bhp (nearly) stage 1 increase is virtually unheard of without other extensive mods.

    WOT?? 340hp on stage 2 using the stock IHI turbo??
    This is not correct. The stock IHI turbo cant do more than ~300hp.
    I also have revo stage 2 on my B8 and I was told it's about 300hp when running on performance mode B.
    Revo stage 1 will only do 300hp when running performance mode C and this require 99/100ron fuel.

    I got my Revo stage 2 flashed like 1 month ago and Revo told me that when running performance mode B I should expect like ~300hp and 470nm.
    I don't know yet if this is true coz I have not dynoed my car. The reason for this is that my clutch is slipping so I need to find some clutch upgrade for my car.

    Audi A4 B8 2.0TFSI 2012 Quattro Avant 6MT
    Mods:
    ECU: Revo Stage 2 Performance B - 98RON V-Power Nitro+ Fuel
    034M HFC
    Milltek Sports Exhaust w/downpipe
    IC Upgrade
    aFe Pro Dry S Air filter
    Eurocode Turbo Inlet Hose

    I have some data from logging the car using VCDS and with my current mods I see MAF values at about 223g/s. Boost is about 1.5bar up to ~4000RPM and then dropping to 1bar at 6000RPM.
    AFR values is about 10.5-11 all the way up to 6000RPM under WOT.

    If you tune your car with revo you can get the SPS box and set the car back to stock mode. I have it and I have tested this. Car feels like stock again and my VCDS log's also is identical to the one I did before the car was tuned so your audi dealer wont notice anything when they test drive the car. However the checksum calc they do will most likely give you the TD1 flag so this you cant avoid. You could try telling them that you got an ECU update only to get better MPG and hope they will accept it :)
    Some other solution is to get a new ECU and get it coded up for your car. Then swap it before you drive your car to audi for a service etc.

    I really hope you are right and that I am wrong. If so then I also might have some more hp on my car. Our mods is almost the same except for your d-cat and I have a HFC + IC.
    Do you run your tune on performance c/3, if so then what fuel you use?
    If you have a 6MT gear box then perhaps you could try to test 80-120km/h in 3rd gear on a straight road.

    Here is my 80-120:

    This was before I got the IC upgrade and the air filter.

    Here is a 2nd gear pull from about 3000rpm and up to 7000rpm.

    All dyno's vary despite correction factors etc.

    The best thing you can do is two runs :

    stock mode
    revo mode

    Look forward to see the results .... hopefully included the boost etc
