For almost over 1 year I had always max boost with my Paxton VR4 on my 454 ci engine of 6 psi and I was happy with it.
But yesterday during a dragrace the boost dropped, it turned out the gasket was blown out between tbihat and the tbi, so I fixet it good this time with extra shims under the wingnut tighten it really thight and guess what ??
It was leaking all the time becouse now I got 8 1/2 psi boost
Now I am back tuning the thing becouse of a lean mixture:teeth:
So what I am trying to say is, are you absolute shure you see max boost ? ;)
