I highly recommend MKPROG33, its manager Maxime is very talented in his field, full of good advice and a price more than honorable.

My companion left her BMW 116i for conversion to ethanol ... result of the races, a more than remarkable reduction in the fuel budget, a motor that makes less noise.

My brother-in-law also made a reprogramming on his mercedes Class C200 for a passage to 200CV

And a colleague of work on his Class A250 ethanol conversion plus a reprogramming of the engine at 250CV

VERDICT 100% satisfaction
