I am not sure but I think my boost has decraese from the day I got my car. If I can remember right, it was pushing 13lbs but it is only peaking at 10lbs and holding at 7-8lbs. I checked for any leaks but nothing was leaking. Anyone know what the stock boost is, I am pretty sure it was 13lbs but i am definitly not seeing that anymore. If I get the Stage1 upgrade does it increase the boost pressure at all? Please help, Thanks

 

Your peak boost with the right weather should be 14psi.

 

If my boost doesn't reach that in the up coming months of good weather, what should i look for.

 

The most comon cause is a leak, tighten all the hoses on the turbo and intercooler and throttle body.

 

heres agood ? did you put in regular instead of premium fuel and what was the temp out side?

 

build a leak tester and actually test the car, don't just go tightening everything down or you'll end up breaking something. even better would be if you have access to a smoke machine, we just got one of these and they're awesome...so much easer to find leaks with.
