I just recently purchased a 2020 2500HD Gas 6.6L and I was wondering if anyone has heard any info about the tuning ability of this engine. I don't tow. And if I do it is a Jet Ski or similar. I was looking for a tune to get more power and better MPG. Not sure if the community has seen anything.
I have checked the regulars such as ; Diablo Sport, 5 Star, Hypertechusps tracking showbox speed test
