Okay, I have had my car running great and then sometimes not so great. A few weeks ago I had the turbos removed so we could redo the studs since they were in bad shape. When I got it all back together I was only boosting about 10 PSI MAX in any gear. It just does not throw me back in the seat. I am thinking it is a vacuum line issue but I am not sure? Is there a process I should go through to see if all the lines got put back to the right place and to check the major ones that go bad usually? I would appreciate any assistance. I am a novice and need directions in pretty easy steps, if you know what I mean...

Recently I also changed spark plugs as well and changed some easy vacuum lines that are easily visible and accessible. I have never had the top manifold cover off to examine all the lines below.

 

10 PSI is the stock level, so it sounds like it is running fine. If yours was higher before, then you have an issue. Try here for a ton of info and all the turbo help you need: http://www.autosportracetech.com/RX-...leshooting.htm

 

This is what you need.
