I just read the Best LMM EFI tuner thread and thought I'd ask about my truck, an LBZ with no Cat, stock intake with A Predator 65 tune most times. I have never run the 120 tune, 85hp once. I don't want a race tune or a pulling tune. I want a mpg or mild tow tune. Am I better off with with my stock Predator @ 65 or 40 HP or should I upgrade to the PPE Standard or go EFI? Any other suggestions?
