I did an engine swap on my dune truck and I need more WOT fuel pressure, I thought I bumped it, but the DC is only 48% and its going below 40psi. I attached a scan and my file. Please look them over and let me know what you think.
I know the MAF is maxing, not sure what I am going to do about that, its the stock MAF in a 4" intake.
Engine Mods:
'07 SC 5.4 from Harley truck, 42# injectors, 4" eBay intake, smaller pulley, Comp thumper cams, headers, ported '08+ heads
