I Have Ordered The Superchip Power Programmer For My 4.6l What Can I Expect? Does It Really Do Want People See It Does? I Also Have A K&n Air Filter And Flowmaster 40 Series Exhaust. Will My Other Mods Help The Programmer? Thanks For Any Info.

 

I have pretty much the same set up as you do with the Superchips programmer. On the 91 octane you notice a pretty big improvement, on the 87 octane you'll get a little bit of a improvement in the way of accleration, however I think it's worth it no matter what setting you use just because of the improved shifting and the ability to remove the speed limiter.

 

it is a big difference with shifting but make sure u have some1 who knows the program shows u cause it can get a little bit in depth. but on my 4.6 on the 91 octane program is alot better
