I am pulling 80% of time at nearly the 22,000# GCWR rating of my truck and I'm looking for a little more pulling power. Which box is best for pulling when using stock exhaust and intake systems?

Note: I will be adding gauges.

I use the Edge hot juice on level 4. If my EGTs go up to 1300 when it down shifts, I switch to level 2. Pulls great. Noticable difference up hills.

Juice for me too! And it if you get the Attitude it's all in one, gauges and shift on the fly!

I have the Banks Stinger TLC Kit and I love it. Pulls our 14,000 lb toy-hualer 5th wheel very well. Has automatic EGT back-down at 1300 degrees and also detects slipage in the transmission and will back down for that as well. Kit comes with 4" stainless exhaust, Ottomind reprogrammer, guages, wiring harnesses, guages and pyrometer, and Big-Head waste gate acutator. I have never had a problem with the stuff, and it does make a big difference when pulling heavy:) ! You can also choose the Banks 6 gun, but I wouldn't tow in anything over 2 or 3.

Juice for my Heavy Hauler in COMP Flavour.
EGT limit set to 1150F on the attitude.
Just floor it and drive!

I use the VA 90/150 and tow my 15000 pound fifth wheel at the 90 HP level. Very seldom do the EGT's go above 1000 and when they do only to 1250. I would not do any serious towing unless some exhaust work was done however.

Banks 6-Gun with S/L.
Level 4.
350 horse and 700 lbs torque at wheels.
No problems.

With stock exhaust I kept it at level 3.
