Tuned my 2010 Sierra this weekend

So far loving it. Since I already had HPT on my laptop went ahead and paid for 2 credits and dug into the truck. One thing I had always hated as how it feels like the power is feathered in when you start from a stop so I fixed that in the tune along with decreasing the shift times on the up shifts and downshifts.

The trucks pull away from a stop alot smoother now, shifts quicker and firmer as well. I dialed in some of the timing tables as well, logs show no knock as of now.

Next up will be messing with the AFM and the torque converter to get the slip out of the converter and get it to lock faster which will help add some fuel mileage.

Truck is a blast to drive now.
