I just installed a whipple with 4" pulley on an otherwise stock 2010 LS3 Camaro, using the Whipple tune copied to the 2bar OS.. things seem like they are working great. Im using the Whipple MSD Boost A Pump.. but who knows if it's working. I'm not running lean under the low RPM I've tested it at so far, in fact I just richened up WOT so the settings I entered to do that work fine.
I've been searching for Fuel Pressure information, and found Injector Delta Pressure, but when I log it, it shows lower PSI when at WOT/Boost than when driving normal, out of boost/PE.
Is this normal? What exactly is Injector Delta Pressure and is it actually reading fuel pressure, or just calculated fuel pressure? All the posts I find about it are confusing.
Attached is a picture of the datalog where delta pressure drops to 58psi during WOT/Boost and stay's there.
