lb7 Tow tune

[mac99]

This is my first attempt at a tow tune for my 2003 Chevy Duramax dually. Low end drivability is great and continues to pull hard up to 3000 rpm.Tranny tuning is stock except for 10% increase in upshift pressures. Take a look at it and any feedback for improvement would be appreciated! I started out the McRat 20/20 tune and muddled thru the rest myself.

But your truck will never make more than 755 lbs torque with this program.

Why do you continue to say this stuff? Just because you can't change the max torque value in the editor to a higher number has nothing to do with how much actual torque you make. If that was the case then LS1's would never make more then 640 lb-ft of torque and with FI, 640 is easy to do.
