Re: 1991 V3500 Project Heavy Hauler
Thanks guys. Installed a vent in the lid of the power steering pump and no more pedal return issues.
Another interesting tidbit: hooked up the obdII port to my buddy's efi live and compared my tune from Howell to his stock L29. Virtually identical except about two degrees more ignition timing at high rpm and load. Still only 17 degrees at 4000 rpm!
