Your thoughts on this problem....

OK, this just started happening, and it doesnt matter what boost Im running... *13psi or 21.5psi*

Spool is incredibly slow...

When I floor it *at higher rpm, like 40mph in 2nd gear*, it's almost like I hit fuel cut, with a violent jerk, alot of noise, and then the car launches, but not as fast as it should...

Everything acts normal, so long as I dont go WOT...

Please, diagnos... Discuss... Opinions...

Thanks,

Boost leak. Split pipe or leaking coupler, I bet.

Sounds like a boost leak of some kind. How old is your turbo? When my last one went out it started spooling slower and slower and slower and....

Turbo's not old, and until I got it, it never saw anything over 7psi... *truly, the guy didnt know how to use the boost controller, hell, I BARELY knwo how to use this boost controller*

Anyway, I think I found my problem, as it presented itself as painstakingly obvious today: blown IC coupler...

Running incredibly rich, puffing massive amounts of black fuel... Im thinking because it's not getting the air to match the fuel being dumped in at that higher RPM...

This sucks, I just need to upgrade my IC piping and go with Tclamps and better couplers...

Thanks for the input guys...
