About Us


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.

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.



  • Over the past 15 years, We’ve made our name with high performance Audis. The experience we’ve gained in these turbo charged cars is invaluable and welcome new challenges.
  • Recently we have produced in-house an R8 V8 Turbo conversion that has dynoed 850ps 1040nm. The car reliably has run 750ps 900nm and will do a 10second 1/4 mile time.
  • We have produced cars that run over 200mph proven and tested reliably at VMAX.
