BAP Fuel Pressure question.
Just curious to see what others fuel pressure jumps to with a BAP.
Whats your idle FP and whats your FP at WOT with the BAP kicking in?

If I see it right (But it is hard to look at it when you are going that fast - kinda dangerous 
) it is at 60 PSI continuously with the BAP under B@@ST!
It keeps it from going under the needed fuel pressure it does not send it to the moon when it comes on! It gives it some extra voltage to maintain the proper pressure!
Thanks,Matt

I have a MSD BAP and I believe its adjustable. I think I have to turn the voltage down cause under 10# boost I was seeing 85psi. I love my SPA gauge, it lets me flip back and see what the peaks were. At idle and under normal driving conditions I'm at 65psi.

Did you change over to the old style return system or get a new fuel system?

If you see 85 under wot, then your tune is probably written with 85 psi under wot.
