This is my first attempt at a tuning a boosted engine. It is a budget build 5.3L with twin 67mm turbos, LS7 cam, 80 lb injectors, Holley hi-ram intake, and ported heads, 4L80E. I have the SD 3 bar OS. I know it is way rich especially in the upper MAP and the timing appears to be quite low by the log especially when it goes into boost. Otherwise, driveability seems pretty good. It's just a dog when in the positive MAP, probably due to the low timing and being overly rich.
I'm getting quite a bit of knock retard that I can't seem to figure out. It doesn't look like it should be knocking, all things considered. I know I need to work on the VE table.
TIA for help and feedback.
