Hey guys,
My mods are on my page. I have two problems.My 1st problem is i recently put in a Big 16g turbo into my 97 gs-t Spyder and I am getting what seems like a loss of noticeable power all around. I have not done a boost leak test yet. When i get on it i have littler power than with the stock turbo. I wont get over 5psi in 1st or 2nd. In 3rd i get about 12 at 4 or 4.5 and full boost in 4th and 5th. I was thinking maybe my wga arm was staying open? And my 2nd problem is I almost lose all power at about 4.5k rpms. I heard it could be from a boost leak? Please help driving me crazy. :banghead:
