What fuel pressure at idle to run? Just installed the champion aluminum heads and the racetronix 680 LPh double pumps with 120lb injectors. Also finally upgraded the return and feed. This is an E85 car. Before on e85 and 80lb injectors with a single fuel pump I was running 52lbs of fuel pressure. Other mods are in my signature.
Fuel pressure line off at idle?

I have the same fuel set-up as you and mine is set at 42 psi line off right now , but I have a hobbs switch that turns on the other pump @ 15psi . I will be dynoing my car Wednesday with Bison so we'll see how it works out . Right now the problem on the street is traction , the power comes on so fast even at a 50 mph roll !!
