Okay here is the story i bought a complete turbo kit from a local shop…that i have been going to for about 6years. well i ended up buying a DRAG kit… well i got the kit put in and ever since i got the kit my car wont Boost passed 6psi dunno why but the shop had told me that it was a bad spring in my waste gate and they went got another spring still not able to boost passed 6psi. so they said it was my manual boost controller but yet they tried to use 2 different ones and still nothing… im getting so pissed off that i spend that much money and cant get the boost that i wan… so if anyone knows what may be going on that can help me ??? :think:
have u checked for a boost leak? bov staying open?
how dose a bov stay open ??
shitty or un-properly adjusted BOVs will leak under boost. It sounds like a boost leak.
What wastegate? What spring rate spring is in it? What are you using for engine management?
turbonetics deltagate mark 2 wastegate 7psi spring, FMU
I’d take another look at the boost controller. Is it installed correctly? How are the vacuum lines hooked up to it and the wastegate?
what exhaust are you running? do you still have the stock cat?
full cat back GREDDY SP and yeah i got a cat but its not stock its a high flow one
Had This Same Issue Come To Find Out My Gasket Betweeen The Turbo And Manifold Was Fucked And Then Also Found Out The Manifold Was Crack.
