Just did a quick little drag against a chevy that had a 5.7 whatever its called. Let's just say there is no comparison. I did the TMS delete mod and that is what makes a huge difference. instead of having the truck dog out when it shifts, it actually kicks now. The best mod ever done. Now for a 03 hemi, is the superchips worth it? I heard it doesn't do too much power wise.

 

Yes its worth it, i have one and glad i bought it, i run the 93 performance tune....its great, i got mine used off of ebay

 

Yeah both SC and DSP are nice. There is a thread in the FAQs on both of them and lots of threads in the forums

 

Nice!


The superchips 3865 made a good difference on my 04. The 03's are different though. Anyway, still should make a nice difference. i run the perf 91+ as well
