does not happen on mine at all

 

it is POSSIBLE to happen to any car but it all depends on the setup you run... usually happens when you have a turbo that is pushing to much for the fuel system.

 

gotcha...basically if you upgrade a turbo and dont upgrade a fuel system then you'll go over the max capacity of the fuel system and the ecu cuts power to it so it wont screw up the injectors and burn up the fuel pump...right??

 

Well did you get a jerk? Unable to get above a certain RPM? A lot of things can effect that. The quality of gas you got... even though you might have filled up with decent gas... thats no telling what you actually got.

2) Temerature has a lot to do with it. If its hot outside it can make fuel cut come in earlier. There are just so many factors.

Almost sounds like a boost leak or something?

 

when i first heard it it sounded like he blew a coupler but if he didn't change anything and is boosting just as much as before than it can't be a blown coupler or he'd still be lacking power. again, are the only mods done to the car in ur sig?

 

Having looked at this again... and hearing Rons theory... Im backing it. It sounds like a cracked/blown coupler somewhere... check all your v tubes and whatnot.

 

well like i said that's what it sounded like before BUT if he didn't change anything (by that i mean repair or change out his coupler) than he would still be losing boost and since he's pulling just as hard now as he was before..... that can't be it. so it was either fuel cut or knock. you ARE running premium fuel right?
