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 S4 B5 has k04 turbos, custom exhaust, 600cc injectors and ebay s4 intercoolers, and xxx tune. It did 299ps 451nm - It would have been less before we fixed the split F hose!

With the MRC Stage 3 Remap it did 435ps and 603nm. The ebay intercoolers are not good for k04 cars and this is stopping it from running higher boost to make more torque and more power.

This RS4 has TTE550 turbos, Wagner Intercoolers, Manifolds, 3" Downpipes, Milltek, 600cc injectors and Fuel pump.

It was in for a health check with an occasional stutter - new EGT sensors stopped the occasional boost drop/over fuel stutter. Back to what it should be - a nice 556ps and 720nm. This is a great all oe turbo response but with over 550ps
