Thanks for the info guys. I had replied in that thread a few times and that thread is what really got me thinking about the tuning/cai. But, Morgan @ Midwest sent me another tweaked file and this one runs like I was expecting it would with the sm65.5!!! What totally blows me away is how basically everyones tunes smoked and smoked bad. Going 50mph and hitting resume for the cruise to go to 70, it would paint the sky black. This thing doesn't puff a bit. Not sure if Morgan pulled some fuel out of it too, or if having an accurate MAF sensor makes that much of a difference. Trans shifting is spot on and egts are lower as well. Thankfully Morgan kept at it and got this thing running hard. Now its time to start adding fueling mods to it.
Hopefully Mike can keep bugging GH for an updated tune cuz I'd like to see how theirs runs just to compare since I paid for it. But does GH actually live tune trucks or how are they getting the tuning info they need? I only ask cuz with the MAF tuning issues I had, all the files they sent me seemed to make it run worse. Also noticed like on the trans files, I'd get one that had a date from like 2013 or 2014 on it and the engine file would totally change its naming convention to e20. So I knew at that point its like pissing in the wind, basically just getting someone elses tune with my vin/device info entered in to make it work.
