Ok heres the prob..... My car wont boost past 15psi. Every time i try to turn my wga up it willl spike 20psi or watever i turned it up to then quickly fall to like 10psi. Then when i go wot again it will only go to 15psi. I dont know wat the prob would be i have ran my wga like agp says and i have even ran my res valve lik an aftermarket blov. I dont think it is a boost leak bc my wga works fine under 15psi and i have checked everything, but i am still goin to do a boostleak test this weekend. My car was fine b4 i blew it up about 2 months ago. I have had it back from dodge for about 4 weeks now. They said they were goin to do an update on my pcm but i dont know how it could be cutting my boost bc of the way i have my vac lines ran. Thanks guys.

my wga worked fine b4 and im not sure if it is a boostleak bc it boosts normal until 15 psi..... and wen i first turn it up it will spike watever then the next time i kick it it will only go to 15psi
and it will stay at 15 every time if u dont touch it and sounds like pcm boost also but u said its not or it could start leaking around 15 just test it

I am goin to this weekend. I hope thats wat it is. The only reason i think it might not be is bc if i turn it up to say 20psi i go out and drive it the first time i kick it it will go to 20psi then fall back to like 10psi just as fast as it spiked it.... then wen i let off and kick it again it will only go to 15psi
yea i know i havent ever heard anything like it... maby it will just turn out to be a leak.... thanks for the help
bump.......
