ive ran gearhead tunes since back in my 6.0 days. loved how he tuned. no smoke and loved his trans file. hated how my mini maxx shifted at set speeds. 4th tq locked at 45mph and 5th tq converter locked at 55mph. worked okay for empty but didnt like it back when i was towing. seemed to lug and couldnt get what i wanted out of the shift schedules. got gearheads trans files and his are dynamic where they dont just shift at set speeds and LOVED them. figured they could tune a single 6.4 but apparently not.
I just talked with dallas @ HSM and he got me loading up the H&S mcc single calibrations. finally got them loaded up and gonna give them a shot tomorrow. only reason i didnt run their tunes from the get go was because i was scared of having to go back to their old trans tuning. Im not knocking the turbo kit, which is why i was wanting to hold off on my initial thoughts until i get tuning and miles on the truck but people started asking questions so i had to kinda answer them lol. I didnt spend all this money to make it smoke, i promise you. if i wanted to blow this kinda money i could have bought me an ol 12v and oral all the coals i wanted.
