Re: question about fuel presure
You might want to include whether you have a speed density or MAF tune, but your 30 lb injectors should have been rated at a certain psi and that probably is 43.5 (stock for an LT1).
descreened maf tune.thanks 4 ur input first time play n with fuel injection still alot to learn.thanks again

FWIW, I've been running the same descreened MAF for 10 years.

Re: question about fuel presure
It's almost never needed in ANY motor to be honest, and is one of the most misunderstood and misused modifications. Even on high HP builds the stock regulator is plenty.
