my car was holding back and poping etc under full boost earlier.the dump valve was sticking sometimes so would that make it run like this?it was never sticking open past 0.5 bar.it did feel crap when it stuck but lift off the throttle ang go again and it was fine.i met an evo 7 and got raped by it because it was running cack.i just took it out now after a fault code check and all clear and it was running spot on again.would the fact that it wasnt getting all the air that was going thru the afm making it run rich mess up the ecu for a short period?
