My pickup originally had a 4.8 liter, now it has a 6.6.

When I originally got it running I just did some basic changes to my stock tune. Changed displacement, copied VE table from a "stock calibration" folder with one from a 2004 6.0 truck, cable throttle and etc. My truck has ETC.

Anyway I want to load the Denali tune into my truck, basically copy the entire computer, since it is much closer to my combo than what I started with, and get all of the ETC, transmission and tables a lot closer to what they should be for my engine. I'm sure when I modified my 4.8 tune to work with my new engine there are probably some tables that I did not change, etc. I think starting off with even more of the "right" settings would help me out a lot. Obviously my engine is still a lot different than a stock LQ4 and I will have to make my minor changes.

I was told the operating systems may be different since it is an SUV compared to a truck. Is that true?
