Hello, today the FPR + ECU came in. Is by the way stage 2. Must say the car runs very nice, only there is still something that doesn’t fit 100% in my opinion. 1. and 2nd gear are really strong. But in the 3rd he pulls the charging pressure back to 0.7Bar to lift it from about 4000 rpm again….what can that be? Today it was exactly 20 degrees outside temperature, so not too warm. While my charging pressure indicator shows e.g. in the 3rd 0.7 bar the original in the tacho is like fixed nail My charging pressure indicator is connected to the vacuum hose of the Bosch BOV. Funny or, much reads, you can now get the “leak” in the tacho everything perfectly, but on the line of the BOV too little charging pressure…….can anyone do something with it? *hust*kater*hust* My guesses: 1.Tünkerzen, there are the original Aero candles in it. Perhaps I need others now? 2.Ferrita irdendwicht? Would that matter at all? (except directly on the turbo) 3.this APC Valve or what that means. (3 hoses) 4.bad fuel? (tank always 98, but this time from cheap tank) If someone still has tips I would be very grateful.:smile: In the stand almost series, during cruise also, at full load…..
