My question would be, which direction does adjustment reduce "torque management reduction"? Does positive adjustment increase reduction or decrease it?

I reside at 9K above sea level and play in the higher mountains. Work is at 5K. It is very seldom that I drop below 4K. At what altitude should I be data logging for the best results?

Thank you!

Hello Guys,

The new updated CROM has a TCM error. Any attempt to modify a saved tune results in a failed modification upload at 56%. Tool states "one unit cannot upload". '08 1500 6.0L is still not available under GMC vehicles. I have used the Chevy Silverado 6.0.

Thank you Mike!

Hello Gents,

TCM file attached. Trinity tool reads "backup may be corrupt" after loading tune. I also had to select 08 Chevy as 6.0L for the vehicle as the 6.0L is not available within the GMC Sierra vehicle option, within this tool.

Thank you

JC

I have a new Diablo that only has the Diablo Tune available. Should I see a 91 and 93 Performance Tune? U7194 08 GMC K1500 6.0
