Hi everyone,
I just had a ported eaton 2.76 upper, Accufab TB, 2600 SCT, 60s, dual SVT focus pumps installed. A/F was good at 11.2-11.5 the thing that is concerning me is the fuel pressure and voltage. Fuel pressure is at 40psi and then WOT it drops all the way to redline, ending at about 29PSI. My tuner is saying it's okay because the A/F is good, and I have asked a few other tuners and they are saying don't worry about it. I just have never heard of fuel pressure dropping being OKAY. Voltage drops to 12V, I did order a 200 amp alternator and am waiting on that. I was thinking there wasn't enough voltage going to the pumps possibly.
I've attached this data log if anyone wants to check it out.
