I have a twin turbo in my z, and yesterday i changed my oil and everything was fine before but after i changed my oil my car is not boosting right. I am suppose to be at 5 psi but its only reading 0 psi. Anyone have an idea of what the problem could be?

 

vacuum leak? check your plumbing make sure all the silicon connectors are tight.

 

Does the car idle rough? That is a sure sign of a vacuum leak too.

 

ok thanks..someone also told me it could be the waste gate.. do you think it is...

 

okk thanks a lot man.. ill have to look into the vacuum to make sure it dose not leak or anything..
