    Mitch I'm sure you know but you should be runnin that afr around 12.5-13 on the juice. Try smaller fuel jets til you get it closer. To much fuel is a lot worse than a little lean

    it has ALOT left in in in the traction dept. i just cant get this thing to hook. i was told that i spun into second on this pass. 125 shot. probably stepping up to 175 next.
    traction isnt a major issue. im awd so it hooks pretty good! a little spinning, but nothing major. i think the bigger issue is the 5600lbs my truck weighs...

    11.6-11.8 is a good AF on juice. 12.5-13 is way to high...

    It made me think that Parker did not like our buddy Mitch. I have been trying not to start arguements though. I knew someone that knew what they were talking about would say something.

    it all depends on who you talk to...i've heard of people tuning to 12.5-12.8 on the juice without any problems at all.

    not something im willing to try though haha. i had my tuner set me right at 12.0 A/F
