go with the custom tunes for sure...When I bought my truck from my friend he already had the bully dog set up. He had never done the trans relearn which the booklet recommended. So i set the highest power setting and did the relearn process. The truck shifted so damn hard afterwards it seriously felt like i was going to drop a driveline or destroy the u joints within minutes. Just fyi, something to be aware of. I know your running a different programmer so ur outcome may not be the same. When I purchased the SCT programmer it was ten fold better than the Bullydog, when I purchased custom tunes from innovative I was absolutely amazed! Custom tunes 100% I even had Eric@innovative tweak a tune for me just recently and it got even better than it was the first time! I second mdub on the changing of tuning right now. Truck should be shut off, then retuned in order to switch perimeters. The trans will relearn after driving for a day or more. Best of luck! p.s. and ya, FART on BULLY DOG from experience!

Give Mike @ KEM a call. That's the only downfall to the H&S, he's the ONLY guy writing custom tunes for it. He is good though, so if you've already got the H&S I say try his tunes out and definitely let us know how you like it.

I got a hold their companys email adress, so hopefully I will hear back soon and get some custom tunes:yeah:
