I would not suggest that setting for the tuners. too much power for trans and too much exhaust temp. I tow with my six gun on 2 and the predator on 40. this seems to tow really well. with good power down low and the banks taking over at the top for hills. I go level 3 and predator on 40 for very flat stretches.
A SC IV or V with a 1057 will be first but I wanted info on the stack. I already know I need a trans up grade. Banks tried to tell me the allisons they tested held 500 hp. I asked what upgrades they did but they told me they were stock. sorry I don't believe them. I want to see if anyone has run this stack for SLED pulling.
