Stage 1, 2 & 3 tuning in Maidstone, Kent
Every remap we supply is built for your exact engine and proven on our in-house rolling road. Stage 1 is software only and usually same-day; Stage 2 pairs the tune with breathing hardware; Stage 3 is a per-car build around a hybrid or larger turbo. Diesel drivers can choose an economy calibration instead. Enter your registration above to see what your car can make — then send your build for a personal quote. Not near Kent?
