Don't let him go over about 90-110HP or the Allison will cry... There are: Superchips, Predator, Quadzilla, and PPE for downloaders; Edge and Van Aaken for harness boxes; and EFI live for custom tuning. I also hear that TS performance has something as well.
The most cost effective will be the downloaders. They can compensate for tire size changes and speedlimiter increase.
The easiest are the harness boxes. 2 connections under the hood on the valve cover and they are on or off. The Edge can be fitted with the "Attitude" monitor that provides gauges, transmission defuel settings, and on the fly adjustability. Edge is getting a reputation for not standing behind their product and they are high $$... The VA comes with 3 settings and a toggle switch to adjust on the fly.
I've never been around the banks product, but for the power output vs. $$ spent I'd say it's not that great...
The other option is EFI Live custom tuning software. It's nice because it serves many of the functions of a Tech II scanner. It can work on the ECM and TCM
