A friend of mine brought me a truck to check it out because they were having trouble shifting to 3rd gear on WOT.
Ok well i took it for a ride and notice that the truck its shifting around 6500 on first to second and 6700 2nd to 3rd, Shifting from 2nd to 3rd the truck bogs down due to the MAF reading way wrong. The MAF parameter on the scanner looks like the Rocky Mountains.
I was on a hurry so i just check it real quick saved the log and the tune. I have study and tune my own cars and close friends cars and trucks and i really like it and i know this truck its tune the wrong way, and it came from what they call a really good tuner with hes shop and dyno. I don't feel like judging someone else work but I'm sharing this so i can see what others say about it.
Truck mods are 5.7, headers, TBSS intake, 3600 converter and 4.10
