Ok an update for the ever patient 6.4 guys.

I've tweaked the extreme tune to see if i can fix all the issues (power and driveability wise) so far. I am hopefully going to get the 6.4 back tomorrow to test it. Today Im going to spend the day tweaking the rest of the tunes, the tow and 50 for mileage and the 80 for both mileage and performance. Not nearly as crazy of an overhaul as the 6.0 but still going to require some time, but don't worry guys I will get it fixed.

The extreme tune layed down 800 ft lbs to the wheels, im going to see if I can squeeze more out of her...after all i did get another 100 ft lbs out of the 6.0 compared to the older tunes heh.

yea sorry guys, Ive had this 6.4 for almost 4 days now and for some reason we are having a hell of a time getting custom tunes onto it. Its been an ongoing battle with it. The 6.4 has a much more advance pcm and tcm then the older 6.0 stuff. I use a pretty complicated program to write these tunes and its being a bastard. Hopefully by the end of the day i will have a custom extreme tune on this truck that i can drive around to see if it fixes the driveability issues, then i gotta tackle the power issue. Don't worry guys you are priority number 1 now!

Thanks Don... Take your time and hook it up good for us!

I'm working hard on your stuff today guys, i got most of the tunes ironed out, fixed alot of things I didn't like etc. Hopefully I will get a truck in here this week to test em and make sure that driveability is good and they put out the numbers i expect

Is there any way to get the trouble codes to clear? I'm running AFE intake with banks dual monster as well and I know the increased air flow has got to be messin with the PCM, but my baby needs air to breath. It keeps telling me unit 2 failed to clear when I clear the codes.
