    I'll check your file, I thought i had flatops high enough, i guess not, i'll let you know, at least that will take care of the rev limiter.

    thanks,

    allen

    With Allens tune and cam It's pulling Hard to 6000.
    Allens tune is great,


    I think my rev limiter is high enough, at wot it's great its just when the truck decides to drop down 2 gears and I'm in 2nd reved right out which is what I really don't want to be anyway.



    I'm going to the track and dyno soon to see if i might need to upgrade my 99 injectors so I can get an update from you after that.

    Yeah, mine has that same issue at times, seems to drop in a lower gear than needed. Not sure if there is anything to fix that....Allen?

    How did the track go? We'll have to get together sometime as i want to see your truck!
