Hi Guys
I have no problem doing my Duramax but gassers are proving to be real difficult in comparison.
Tried doing my brothers 2005 GM 6.0L Crewcab. He pulls a holiday trailer around and at 60mph (100kph) he just cant keep it from shifting down into lower gears ... the higher the speed he tries to go the worse it gets . It just doesn't have the nuts to pull. I used to have a 6.0l gasser pulling an even heavier trailer and it would run circles around this one.
I have attached the problem tune to see if any of the guru's here can see if they can help. It was a problem before the tune and appears to be afterwards too. I didn't do too much to the tune and suspect nothing I did helped. The truck is completely stock except for an open intake filter to help it breathe
Maf codes disabled because the new intake kept setting codes..... MAF sensor is operating within values and not a suspect in this problem
All he wants out of his program is more power to pull and if possible better fuel mileage
Any help appreciated :)
