What RPM stall should I get for a 5.3 with air intake, headers, catback, and Nelson's tune? I do not race the truck (2003 ECSB 4x4) but I do want as much stable/reliable torque. I also use it off-road now and then so I'm not sure what stall would be good all around??

Also, anybody have any experience/ advice with Monster transmissions?? (4l60E/4l65E)

Thanks
