I posted this in the 6.7 section too on the gear head thread but figure I better put it here too.

Took my truck with the gear head tunes to the track this Saturday
I made 4 passes with a best of [email protected]

Scaled the truck before I ran at the scales right across from the track. This weight is with me and a 150lb passenger. The passenger rode with me on the first pass then got the other 3 on video

I took my tool box and spare tire off are the only weight reduction I did from my every day driving. Truck had just over 1/4 tank of fuel

All passes were done in 4wd
First Pass with the passenger along. The 2nd pass was my best run of the day

Pass number 3 I had water on the tires and tried launching at a little higher PSI so I spun and hopped off the line. Red lit on top of it for my worst run of the day

Pass Number 4 I tired using Manual mode and launching in 2nd gear at 10ps and shifting myself. I need more practice at this for sure

Over all I am pretty happy with the results. Had one decent 60' time and the truck launches and pulls great till the top end where the stock turbo just runs out of air. I need to get back some time and use manual mode and shift the truck sooner to stay lower in the rpms to see if I can get some better times out of it.
My passenger with me even made a comment on the way home how well the truck shifted going down the track though. Shifts were prefect with the gear head tunes. You can see smoke output in the vids as well. Keep in mind the truck is turing some pretty heavy wheels and tires too.
