My question is what psi do you guys run on your fuel pressure regulators.

Ok, my 3.4 swap is finally complete on my 87 s10 blazer 4x4. I started it for the first time today and it was running very rich. I had the intake bored and put a throttle body from a 88 4.3. The only thing other than stock I am running is 1.6 roller tip rockers.
