Basically when i put my foot down in say 3rd or 4th in comes on boost fine up to 0.8 bar. However it feels like the car is holding back .I can feel it loosing power then being fine again on and off a few times. But the boost stays fine at 0.8 bar. Ive just had the timing belt done could the timing be out slighty ?? Only problem with that is im sure it was doing it slighty before i got the belt done aswell. Only other thing ive had done recently is a japspeed mani and decat. Im guessing its a fueling issue maybe ?? Thanks, Andy
