Fuel issues I have a p1sc1 blowing into 427 stroker at 14lbs boost.
Tuning issues:
It's losing fuel pressure at the top end but inconsistantly sometimes drops to 20lbs, sometimes 40lbs or inbetween (from 65).
Have a (brand new) Walbro 400lph pump in the tank with a MSD voltage booster. At one point it overheated? and stopped all together.
What should I have them check other than that the fuel pump was bad outta the box?
If the lines are too small? Fuel pressure regulator? MSD doesn't play well with Walbro?
What combination do you guys have? The Walbro 255lph with racetronic wiring harness couldn't handle it... should make 700hp to the wheels thru a 4L60E.

I am sure you will need Twin pumps to support the power you are trying to make.
I know MikeP2002 is running either twin or triple pumps in his Procharged 383 C5 and he makes right around 800rwhp.
I have been running twins in my F body for a while now
