Question, Is it normal to have to bump the main scale on the gen II by 37 to get the blms down to 128 at an idle with e85? I have stock long block, pt67 turbo, lt1 maf, extreme front mount ic, 80lbs injectors, and 100% e85. Another question, is 21 degrees timing for all gears ok, or should I go higher in the low gears and stick with 21 in drive to start tuning?
