[QUOTE="drunk on diesel, post: 1343304, member: 2558"] I'm not trying to offer complete tuning packages at this time. You might contact GH to send you a towing engine file. I believe they've done this for other people in the past. My thing right now is trans tuning. I feel that I offer a solid upgrade in shifting vs. the GH trans file. And that's not to talk down on GH. I have run his tuning on all of my trucks and will probably continue to do so in the future. But I have been driving 6.4's exclusively for the past 5+yrs. I've had CCLB CCSB and reg cab trucks. I have had a lot of windshield time in these trucks messing with trans tuning. I have 6.7 tunes also, but the 6.4 takes a lot more finesse IMO. The lack of cylinder head flow and the large amount of boost required to make them go means trans tuning is more critical when you're dealing with a cleaner burning tune. You can throw the kitchen sink at the bottom end fueling, and a 6.4 will move with any old trans tuning actually. But with a cleaner engine tune, the trans becomes critical to getting the truck moving sufficiently. [/QUOTE]
