Car was having fueling issues went from 2+ to 1+. replaced lpfp with walbro 450 but problem persists. load actual < load req. turbo lag (no boost below 3.5k). Throttle Closure. Overboost. Car has faulty alternator and the voltage drops below 12V while driving (might be one of the cause). Custom tune needed. (car cuts injection to engine if pushed hard when lpfp pressure is dropping)
