Hey all,

I just pulled off my Holley FPR last night, because I couldn't get my car to run like it did with the stock FPR. The stocker reads 31 at idle, and 40 at WOT. (no vac) I tried everything from 30 / 39 to 38 / 47 on the Holley and the car just wouldn't run like it did before. (and now)

What would you recommend for fuel pressure & timing with the following mods?

'98 Explorer SB
GT40P heads (shaved)
Cobra upper
Ported Cobra lower
Cobra roller 1.7's
Stock SSV cam
Pullies
Flows
CAI

Car ran 13.11 @ 106 with my old, chipped up Pirelli P600's, with 1.9 60's.

It'll be well into the 12's with the new Nitto 555 drag radials that were slipped on the pony's last night.

What do I stand to gain if I can get it tuned with the adj FPR?

Thanks in advance...
