Stage 3: Stage 3parts +2 Big turbo + Decatalyser
Stage 4 and +: Stage parts + High flow 3 injectors + reinforced clutch, forge engine internals.
The tuners have their own engine engineers, to guarantee a personalized development, with a gain in performance and engine reliability in all circumstances. They also have their own technicians, to be able to offer you periodic maintenance operations or the installation of performance parts.
Reprogramming aims to increase the engine’s performance by increasing its efficiency, and also to reduce fuel consumption.
The electronic control unit (ECU), controls the whole engine. Reprogramming consists of modifying the internal programs of the ECU via a computer, such as fuel injection, ignition, knocking, richness, air flow, etc..
Thus, after tests and measurements on a test bench, the tuner can intervene on several parameters such as: the speed, the turbo pressure, the opening of the injectors, the richness, the intake and exhaust temperatures, etc..
