Cutting Out

[bazz]

hi i have a r33 gtst with a cat back exhaust and pod filter runign stock boost. when ever i rev it above 4000 the boost sounds like its leaking and then it cuts out as if it hit the rev limiter, i change to 3rd gear and it does this at 3000!!!

ive changed the sparkes inspected the coils (no cracks or scortch marks) ive chekced adn tighened all the pipes from the intercooler to the throttle. im stumped, any help is much appreciated

yeha mate i changed the afm with another mate, and it was alright. i think its an air leak from the turbo, cuz when u gear down from 4th to second it can ev to 6000

but if u give it soem petrol (and hence boost) itll make the airleajk noisse and missfire/cutout

how do u check the petrol pump?
