i have a 2001 gtp. i"ve noticed on alot of videos of stock gtps running that the boos meter is full at WOT. mine boosts one square less at WOT. Is that normal or is there a problem?
 


also, could be a vacuum leak. Under you supercharger snout, there is a vacuum T and it holds two lines. one goes to the fuel pressure regulator (on your fuel rails) and one goes to your MAP sensor (behind the blower) if it has a leak or is cracked then they need to be replaced. Check these things and it may solve your problem.
 
Cool ill check the vacuum lines. What is the bpv? Also I was about to change a worn supercharger coupler. Could that be a problem too?
 
My car did the exact same thing for about a year and then about 3 weeks ago my supercharger went to total **** and i had to replace it so it might a good idea to try the coupler but when changing the coupler be careful not to rip the supercharger gasket because if u do then u have to take off the supercharger and do what i had to do and it was a pain
 


I found the vacuum leak. My bro... Also my mechanic said he had made the the hole to correct for too much pressure in the vacuum lines. He says without the intentional leak my check engine light will come on saying there's a problem with my egr. The comlete vacuum system has been replaced. Along with the egr and maf. He says he doesn't know the problem. But for now I have full boost and I'm saving gas again..... Oh and yea the coupler is gettin replaced this weekend. Hopefully everything goes smoothly
