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.

Chris Stowers1129nm....what about the gearbox?1 week ago

Shazad HassanI got a 'gorilla tuning' remap, full 3.5" Capristo exhaust system and 200 cell racing cats, ITG panel filters, 2bottles of Slick 50 in the first oil change with Mobil 1 0w 40, Moly Slip in gearbox oil, 2 litres 'water-wetter' chemical in coolant system, Kenlowe radiator fan, triple carbon coated glass fibre bandage wrapped entire exhaust system up to backbox. Not sure what BHP or newton metres I got but everything was done after the remap last summer. The rolling road on the remap in Poland whilst I was nearby in Germany, showed 670bhp. I would have thought the other stuff would have pushed me past 700bhp??1 week ago

Paul ClarksonAny strengthening done to the transmission? That's a lot of power & torque for an Audi slush box. Had 2 boxes fail on my C5 RS6. First when it was stock & the second post fettling😫1 week ago

Shazad HassanThe 400bhp car will probably benefit from a higher power/weight ratio depending on its mass3 days ago

Shazad HassanFound an Italian ex-formula 1 composite laminator in Norfolk and has quoted my £2000 for a bespoke carbon fibre bonnet on my rs6 c6 avant subject to me delivering hi a genuine Audi used/new bonnet for templates his moulds. He mentioned he could do them for £1500 if I could organise a group buy of a minimum of 10 units. The options I asked him for were louvred vents in key places where excessive heat build-up occurs and induction air is required. I have highlighted these issues using my flir camera.1 week ago
