Could be better
on March 30, 2013
I expected this to give me more MPG, it didn't. It did however make the truck quicker and change the shift points.
I had a little surprise when I removed the programming (back to stock settings) before selling the Tahoe. The truck started having VERY hard shifts back at stock settings. It didn't do that before the programmer. When I put the programming back on, the shifts became normal again. I always had the settings at conservative levels. It may be just my truck but it was a surprise. I had to leave the programming on the truck when I sold it.
