You unfortunately are going to have issues if you're trying to custom tune that 03. You'll have to use Diablo for custom tuning (only 1 that works on an 03 hemi, SCT isn't compatible). Diablo can't lift speed or rpm limiters nor adjust idle. There has also been a rash of people who have had PCM's and ABS modules burned using it. There is a guy on DT with an 03 who was a serious Diablo nut-swinger until it fried his PCM...

That all being said, Sean will give you the best quality product he is able to. He came up with tunes for the 3.7 in my wife's Liberty, totally worth it.

And with that I'll think I'll hold off until i get a challenger or something after graduation. Plus my dad hates tuners and would never let me get it in the first place. :thumbsdown:
thanks

Get a Superchips, a 3815 or 3865. It's a noticeable difference and the best all around tuner for 03's.

would the cortex 3950 work well also?

It would work just fine, but wouldn't be worth the additional expense since you wouldn't be able to take advantage of all of it's features.
