I dunno the jet chip I plugged in made a noticable difference! Also the cold air intake did too! I guess anything over that your looking at supercharger or nitrous. Not in to blowing up my engine just yet!! Thanks for the replies.

 

lose the jet chip...your gains that you are feeling are from the intake. Ive never heard of positive things from the jet chip...most of the conversations go something like "well...I paid for it so im using it."

Aside from supercharging/NOS like you mentioned...there are plenty of things to bring the hemi to life...

Catback exhaust
Headers (full length)
Y-pipe w/ high flow cat
Hypertech Prgrmr III / or wait for the new superchips later this summer.

these modifications along with your intake will easily yeild 410-420 hp and well over 450 lbs/tq

 

I got around 2K miles on my STS Turbo, making 450 Rear Wheel Horse Power.

You wanna go fast; You gotta pay.

 

As I and others have said before, "Speed costs money; how fast do you want to go?"

If there were really cheap, easy ways everyone would do it, including the factory.

 

Well, DC didn't exactly make it easy for us either.[&o]

 

I used to have a Jet stage 2 chip before I went with the turbo.

I definately felt an improvement with it, and lost that feeling when I took it out. I did something, not much, but something.

 

Honenstly, unless you put somthing that gives you atleast 30-50 horse you probably won't feel it. Especially, when your working with such a big engine that already has so much horse. I didn't feel anything when I put in my CAI but, that dosen't mean it ain't doing nothing. Thats just my 2 cent.
