How would adding a adjustable one on the return line allow for more psi to flow through the stock regulator?
Not questiong you, just wondering how that works.. isn't the regulator...supposed to regulate it?!

Basically he's adding pressure to the whole system by pressurizing the return line.

Oh and Brian, my stock reg is the adjustable one. As for the pumps, you and I should both have TBI pumps. Spec is 9-13psi.y new one is 50+ out of a Camaro.

Update. Had an extra vehicle to drive while a friend of mine was out of town, so i had a shop get the new fuel pump in. Not much of a difference, because of the timing chain possibly losing tension, and needing a chip, but I could swear it has better pick up now.

Also, same shop found my passenger side motor mount destroyed, so I'll have them replace both while I wait to hear back from Mark at Gearhead.

Been running her on the stock tune since I did the build. It took a few months but the computer adjusted surprisingly well despite being on the stock tune. I can light up the tires at 30 on a smooth road and she launches like a bat outta hell. Next step is a huge cam, full exhaust (already snagged a set of longtubes), and Holley 750 and I'm gonna beef up the ignition a bit. Still leans out pretty bad at extreme WOT, so a wideband is also in the plans.

Haven't been here in over a year, wow. Small update, still running the same engine setup, now shopping for cams because I found a local guy that can tune it. Oh yeah.

waking this up from the dead, I know. But, did you ever get it tuned and how did it perform afterwards?
