Idk but I do know with my current MPG tune (bought it still haven't gotten the hang of building tunes) I'm pulling a hair over 24mpg on my LLY
Also looking for a decent B/ATDC timing % for a fun street tune....and why is it that when I put my main inj pulse table into the timing calc I get some HIGH timing on the big/high RPM range
Dustins but these were ideal conditions (no AC, all freeway and cruise at 65)
