Default 03 ram 5.7 hemi programmer question

hello ram owners, i have owned my 2003 ram QC 5.7 Hemi for almost a year now and i think its time to buy a programmer. Ive heard very good reviews about the diablosport predator and the superchip (not sure what model). I have also heard that the 03 is the hardest to program, so i am not sure if it is worth spending 300$ for one or not?? The lowest ive ive priced the diablo for is 270$ and the SC is 330$. I read that the predator has been discontinued and has been replaced with the intune(which costs 400$). So im wondering if i should hurry up order a predator while i can still find one?? If a programmer is not the way to go on the 03's what mod should i do? Im looking for better mpg and possibly a few extra ponys. Any help would be greatly appreciated! Thanks

Superchips all the way with an '03 Hemi. It's the only one that can raise the RPM redline and 105 mph speed limiter. Neither have any transmission related features.

x's 2 on going with superchips for your truck. You would also be better off buying a used one and saving $150 or so. Just make sure it has been reset to stock.

You can get a used 3815 for fairly cheap and it will pretty much do everything that is possible on an 03.

Agreed, I see the 3815 going for as low as $100 on other forums.

I have to disagree with frostking. I have the Diablo Predator Sport, I bought on craigslist for 200 and couldn't be happier. Mine is a 04, production date is 03. I was able to raise the redline limits and the speedlimiter in my truck was originally 90 mph! it's now 190 (even though I haven't seen that yet). There is no transmission changes though.

You can disagree all you want, but you're still wrong. This is why: yours is a 2004, doesn't matter if you have a build date in 03, you don't have the same computer setup. Diablo has admitted that none of those features will work on an 03. I can also tell you from trying it myself that it doesn't work. DSP WILL NOT raise the rev limiter on an 03. It also WILL NOT raise the speed limiter on an 03 because of the seperate ECM and TCM. It will do these things on yours because you have a combined PCM. You can load custom tunes from a DSP on an 03, but you are stuck with the stock shift schedule, rev and speed limiters. If you don't mind shifting at 5700 regardless, only being able to do 105, frying your ECM and/or ABS modules, then the DSP might be for some people (do a search, it's happened). Only reason I still have mine (I picked it up for a song) is I will need it when I convert my 03 setup to an 05.

Go to this link:
http://diablosport.com/index.php?mod...isplay&pid=150

It shows what is enabled for what years. You will notice MY2003 is very missing.

Im pretty sure I will be going with the SC 3815, I have found several for under 100$ and from what yall have said and from other info I have read it is the best bang for the buck. Probably going to install a shift kit for firmer shifts since no programmers have the ability change the shift points.

You do have the ability to disable the torque management.

Shift kit will give you quicker shifts but not firmer shifts. At least that is what goes for the trans go kit.
