In August I installed JMBperformance's 3in CAI. I also have Stage 2 w/o toys. the car was running fine until I noticed that some of the lines to soleniod #3 were damaged. I can only assume because they were moved because of the CAI not having a bracket for them. The line cracked right where they would connect to the solenoid (a little rubber piece goes over a nipple on the sole.) the cracks were letting air escape causing there to be 2 to 5 psi. I used zip ties to hold them in place until I could get it fixed, which by the way was not covered under warranty but I knew that going into it. the ties held fine and I was peaking at 17psi and holding 15 with no problem. The problem now is that I just had the entire harness(every line to #1,2,3)replaced and #3 solenoid and I am only hitting 8psi and holding it. I have stage 2 and should be hitting well over 8psi. I am taking it back tomorrow but the mechanics dont drive it hard to see the problems. Is there anybody that could give me any input as to why such low #s? would you need more info?

 

nevermind. I found the problem. Mech put the wrong line to the wastegate. smart guy huh

 

That is why I do my own work - there are too many bad mech.'s out there.

Glad you figured it out.
