Default need help improving 03 5.7 CAI? Tuner?

I have an 2003 SLT. I added a leveling kit and 35's. Now I want to work on the engine. I am looking for a CAI and tuner but there are so many out there. The truck is an everyday driver that is used for work and towing sometimes but not heavily. I just want to get a little more power and better runnig truck. Any suggestions?

I had and 03 5.7 and I installed a Flowmaster, Hypertech programmer, K&N CAI. I think that the Diablo makes a programmer now for the 03 5.7 It's probably better then the Hypertech. It defiantly pick up in the hp department how much I don't know but it was real noticeable.

Check out the Volant line for a nice, effective intake that insulates the intake air from underhood heated air. Some models also have optional lower feed tubes like the one I have on my Chrysler. BlueJet also just got a prototype put on her Nitro you should check out. I have one on order for my 5.2L Ram.

As far as programmers, I highly recommend the DiabloSport Predator if they make one for your year Hemi (and I think they do) as they are much more flexible programmers with a lot more options than the canned tuned Hypertech and SuperChip offerings.

I just wish they made one for my older 5.2L Ram. I have one on my Chrysler 300C SRT8 and hands down, everyone on that Z forum will tell you the same thing... Get A Predator!
