more boost leakings..

[krush]

hello all,

not so long ago my car was losing boost etc and it was said its the head studs and gasket. i got that fixed (5 of the 12 were snapped) and after that its had a major boost leak tothe point it wont boost over 5psi and runs crap after that (which is usually around 3000rpm).

i had it in the shop today to fix the 'supposed' problem, a rubber 45deg pipe going into another rubber pipe and clamping it wasnt working.. so its all been replaced with steel and such, but now its still happening, just not as bad. with my foot flat, it will hit the 5psi, sound of air leaking, but still rev, just not as powerful.. where as before it was just bog down and not go anywhere really.

obviously, ive checked all the pipes, clamps, etc, and im sure the guys at the shop would have checked them all seeing as theyd have taken them all out, so, where else could the problem lay? could the studs not be right or something? something not tight around the exhaust manifold?

thanks..

shaun.
