The Predator is very good, especially if you have internal mods like heads, cam, etc. I love my Superchips Flashpaq. IMHO it is the best for bolt-on type mods. The Flashpaq model 3865 is going to have transmission tuning features. The guys at Superchips have really done a great job with this. Part of it will be setting up and down shifts at part throttle and WOT along with reducing or completely eliminating torque control. The other guys I know who are beta testing the 3865 transmission stuff say it is fantastic and really makes a huge difference. I'm looking forward to my part of the testing.
