I have a 2004 2500 with the 8.1, 4.11 gears. I am pulling a 12,000 lb. RV. What are the member recommendations for a tuner? I am looking for more torque, speedo calibration and shift point adjustments.
It turns out my buddy has EFI Live and can help me out. I just need someone to write the tune to my needs seeing that we know just enough to get ourselves in trouble.
I'll keep everyone posted with our results whether good or bad.
