So, for a week now I’ve had my little Wimmer chip in it. First of all it’s to say that those at Wimmer in Solingen are super friendly by the row. Then I had a Forge valve and a K&N filter installed. Mr. Wimmer drove the car at the beginning and looked through. LMM was defective. Low pressure hose was porous and I had a Marder bite as well. Was only at the inspection at the friendly before 6000 km. After the chipping there was then again n E test drive. In the week he is in now I have to say simply: Suuuuuuuper!!! The suit is simply goil. Every tap of the gas pedal is immediately noticeable. Engine runs very quiet and the consumption has decreased by 0.5 liters. To the Vmax: unfortunately I can say nothing. (winter tires). Bottom line. Top performance of Wimmer. Oh yes; Audi forums members get Rabat!!!
