Ok when im in second gear up above 4000 rpms my boost gauge almost pegs the gauge, im getting like 14 1/2 psi. in 3rd i get like 13 and 4th like 11. this is wierd because my car is stock except removed air scilencer. also when i get up to high rpms my car feels like it loses all its power, but if i shift to the next gear(the rpms go down) and it comes back alive. until you get high rpms again. is this exhaust restrictions? somthings up i think unless the SC becomes half gutless in high rpms. also at idle my vac reads 15. i know it should be 19-20. boost leaks? then how would i get 14 and 1/2 psi top end? runs pretty good other than that. small oil leaks. i may have a blown head gasket though because i keep getting more oil on the stick even though i have oil leaks. but that may be a different story altogether.
