Tunit entered the Petrol Tuning market in 2016

18 years after pioneering diesel tuning. Despite our late entry we introduced a ground breaking flexible product with features of adjustment and transferability unlike anything else. The Optimum Plus can be transferred to an unlimited amount of vehicles at no extra cost. Adjustment is via our phone APP allowing a choice of performance and economy settings.  (Eco, Sport and Sport Plus) These features are unavailable on any Map, remap or Chip.  The Optimum covers over 5,500 applications worldwide. If we do not cover yours we will write a file for it.

The Optimum Plus provides all features.
