I also seems to be having another problem now . The car was fine for about 2 weeks just over fueling a bit, I had this happen before I reset the ecu and it started happening again yesterday, where basically when I'm in 3rd ,4th and 5th and try to floor it the car boosts to 1 bar but it has no power and it kind off gets stuck at 4k-5k rpm. I doubt it's a boost leak or anything as it boosted fine for weeks. Any ideas on this, could it be also due to over fueling ?
