I'm thinkin either one of the pumps is bad or a relay came undone on one and it's just cycling one pump through

Well everything else was fine. Injectors picked up the slack and the AF was 11.6 all the way. Only dynod up to 5700 and made 478. Going to figure out this fuel pump and come back and get another 1000 rpm out of it and hopefully hit them numbers I was expecting. Might also switch pulleys to the 2.75 to make up for the compression drop. So no winners yet lol

Do you have a fuel pressure gauge? When I had one of my walbro pumps go bad I had next to no pressure 5-10psi, the one pump will flow back out the other, barely enough to drive the car so I doubt thats it. Im leaning towards a tune thing if not check the hat and make sure the connections are good.

Amen to that. Lost a clamp on one of my pumps.

hey man, check your voltage tables for your pumps.

i have had a problem with their tunes maxing out a gt500 at 500 hp and twin supercar pumps at 550 HP.

It stayed right around 13v which is about where it should be I believe. I think the Aeromotive Stealth's are rated at 13.2?

Plus I have a BAP still on there to help out with that.

I honestly think they aren't accounting for one FPDM and 2 pumps. Although Caleb says he did account for that. If you divide the duty cycles by 2, that sounds a bit more right...47% at idle would be 28% and 95% at WOT would be 49%, which at ~500whp sounds about right for twin stealths. A/F, voltage, and FP are all good...
