    PE (WOT) or cruise? With all those mods you'll likely need to tune your IFRs, then SD tune, then VE tune, then timing, then PE...

    Anyways, factory WOT is about 11.5 and mileage isnt terrible at that rate. There is power to be had by leaning that out to about the 12.5-13.0 range. As for cruising, 14.7 (stoich) is ideal. Then comes in the conversations of DFCO tuning...
