timba, perhaps you'll appreciate advice from someone who has NEITHER an MTM or MRC remap. Of course I don't have an RS4 either, but I don't think that is relevant.

Firstly don't worry about having a remap done by one company and servicing done by another. None of these companies have the time or inclination to care about if a car they are servicing has had a remap by a competitor.

Secondly I think you are actually not comparing eggs with eggs.

One of the reasons that I went to AmD for my remap instead of QST, is because (at the time) AmD were doing at least a small amount of customisation in the remap, whereas QST were very much providing an off-the-shelf MTM remap. Yes I know that MTM have close ties with Audi, however for me a very good map done by MTM with Audi support on a car in Germany, then transferred onto your car, cannot be as good as a remap tailored to your own car.

Now since MRC came to the UK I have been following the development of the company (especially now that AmD have expired). It is clear that they have the capability and willingness to do a full custom remap on your car. Not only is it custom, it seems to be excellent value for money. And finally, at least for the S4 remaps, it appears that MRC's remaps have an edge in performance (based on FATS).

When the mainstream offerings (for the S4) were AmD, APR, Revo and MTM, I felt that really there was very little difference in the remaps of competing tuners. Now that MRC is on the scene, I no longer believe that to be the case.

Yes - well put Dippy

indeed, and not forgetting that their maps are a lot kinder on the turbos too...(I believe that the likes of MTM, APR, and Revo are quite aggressive in terms of increased boost levels)

MRC is 650 for a custom remap and MTM 950 for a generic map. Generic maps are always tuned to less power to leave a saftey buffer as every car is different, has different tolerances and milage.

So, mrc is cheaper and you get a perfect suited map for YOUR car! You do the math ....

Dippy, I really don't think much of the FATS test, it would be quite easy to map a car to be quick in this test but drive like a pig in real world conditions. I mean, how often do you do 4200-6500rpm?

I do 4200-7400 a few times a day, everyday, in 2nd, 3rd, 4th and even 5th gear when I get lucky

Agree with that!

I feel my car runs better in the mid range rather than the higher revs, but thats because the current map I have is pants. This WILL get sorted

HI Guys

I know this will make me sound thick but I must ask what the hell are "FATS" times ? and how do I record mine.
My beast has a Revo map and I bought the car with it fitted,all I can say is

bye,bye most cars on the road and its being run in at the moment,also thank god for uprated ankers.

Cheers "Bingo"

FATS test is the most accurate way of checking a cars real world performance. I dont see how a simple "remap" could make daily driving bad yet FATS time better. There is only so much timing/boost you can relatively run with any setup... the chip/tuner that manages to get the best balance will get the best power results, economy results and best real world driving experience.

If you are not interested in performance over 4200RPM then there is not much point to a remap anyways. So far, MRC results have proven to be amongst the best.

There are quite a few people on the S4 that have moved from one map to another (Moved from AMD, MTM & I am sure others) and they have all seen an improvement over all. I hope they post their experiences in here. Unfortunately these were on S4's rather than RS4's - but the same principal applies.

It takes no account of turbo lag!

Then we have gear ratios, S4 has a longer third gear than an RS4 so can they be compared and to confuse things even more some S4s have RS4 gearboxes!
And I don't mean to be a party pooper but isn't 6500 rpm in 3rd gear well in excess of the 70mph speed limit

FATS is a much better measure that a dyno or even track laps.

Any car built primarily for road use should be on full boost at 4200 rpm, right ?

Gearboxes are an issue in determining FATS times, but for the B5 cars, there are only 2 options so its not really difficult.

Do you always stick to the speed limits then ?

If you have a better means to measure performance, they we are all ears.
