If you're not planning larger mods, then the Flashpaq 3865 is a great choice. The 91 tune will give you about 18HP/27TQ.
Torque management reduction is built into the tuning. The TCM tuning really wakes up the transmission shifts. This is where Superchips shines.
You can later upgrade to the expanded trans options, which allow you to expand on the already great TCM tuning. With this app you can control all part throttle shifts (1-4 up / 2-5 down) and you can tweak torque management even further via PT and WOT.
The Flashpaq is also user friendly. There's a quick tune option for folks who don't want to use the advanced tune options.
