Put together a good tune....

Mighty HD · June 7, 2005

I am 90% on Nelson's and 10% on Westers. Nelson's I feel can get a better tune from the hundreds of thread's that I have compared. With that in mind here's what I'm working with

04 2500hd 4x4 ext cab shortbed. 6.0 auto. Everything is stock. I *might* add a quiet magnaflow exhaust and an airaid intake one day. That's if it really even helps out. I may just add the exhaust and put the airaid intake tube on.

Disable Abuse Mode

89/93 dual tune

Remove Torque management 80% (engine/trans) 100% of engine/transmission in tow/haul mode--keep shifts firm like original factory tune while in tow/haul mode.

Still allow me to tow if I need it---another 4wd on a tandem axle trailer...

No speed limit

No fuel shut off for vehicle speed

Rev-limiter 5800 ???

Shift firmness the same as factory

Shift points the same as factory

What else? Help me put together a sweet tune. I'm looking for performance/a pinch better gas mileage. Performance comes first. Torque management blows. When I nail the gas to the floor, I want instant response. I know it's not a race car, and it's not going to be treated as one. I baby the truck, have had it over a year and haven't even broke 10,000 miles. When I need the power I want it there.

I thought about 100% removal of torque management on the engine/trans in both the tow/haul mode and regular.

Help me out men...

I think you could remove a pit more transmission TM. Leaving the shift points where they are is a great idea on the 4L80-E transmission in stock form. The 4L60-E is good at transferring 360 lbft at 6100 RPM, but the 4L80-E falls short in revs at 420 lbft @ no more than 5200 RPM. Anymore than that and you may be needing some upgrades.
