MRC Tuning Limited is a tuning house based in Banbury, Oxfordshire. We pride ourselves on our technical knowledge and ability to do our mapping/testing/fabrication in house.

Dougal Bennet and Mihnea Cotet opened the UK business in 2005. In 2010 MRC moved to new premises with 3 ramps, 4 work bays, a state of the art 4wd dynomometer.

We’ve made our name with high performance Audis. The experience we’ve gained in these turbo charged cars is invaluable and we now produce cars over 850ps+ 1000nm+

Our resident tuner, Mihnea Cotet, has been at the forefront of tuning Bosch ECUs and VAG/Porsche for over 10 years. This means you get the very best map that is smooth, powerful and most importantly safe as designed by us.

This RS3 8V has TheTurboEngineers TTE625, hpfp, front mount and  CM Tuning turbo fitting kit, supplied and fitted by Chris at CM Tuning.

With the MRC Stage3 Remap and MRC Stronic Remap this does 589ps 749nm at 1.9 to 1.8Bar on 99ron fuel

I thought carbon cleaning was a bit of a myth! Have you ever done a before and after dyno to see if it did anything

Aaron oh wow the over run.

Do you have an pop/crackle map for the S5 3.0 supercharge engine?

Whatโ€™s the performance figures....?

can you please please post a better pic of the dyno chart? im interested for my rs5

Simon nice sound but no where near B8 S4 Stage 2 performance ๐Ÿ˜‰

Christophe Ruineau โค๏ธ

402bhp before, must of been choked with carbon. My V8 S5 made 396 bhp

Mark Brodie

Sounds good. 402 is low! Mine was 440 after 40k miles then did 467 with HMS/Milly and eventuri. Why does it not crackle on the overun during the dyno only when reving it in neutral?

Hi can anyone shed some light just bought rs4 supercharged on the add it listed a revolution carbon air intake as was on when I viewed to discover it as been removed by seller when I questioned why it was removed they told me that I can have the part but not to run it with the updated intake as it will result in big problems and expensive engine repairs due to the maf sensor not being able to cope with that system and to run on standard Audi system what's your opinion it's as I said supercharged stage 3 MRC remapped
