Ok guys, I need your advice. I've got a '97 4x4 with 5.9 and I'm desperatly seeking more power. I've already spent a couple thousand making the "cheap" and "easy" mods that have always worked for me in the past, but have noticed very little improvement. So far, the K&N FIPK and Borla headers & exhaust seem to have helped the engine breathe a little better (and I mean a little) on the top end, but I noticed no improvements from the Jacobs ignition. I was told by a guy with a supercharged Dak that the stock computer counter acts every change I try to make, but mopar performance doesn't make a pcu for 97 4x's. Another post on this sight said a 2wd pcu will work. Anybody have any experiance with this? I'm considering heads & cam, maybe TB, or even a supercharger, but I don't want to throw more $ down the drain. Not going to make any more changes if the computer blocks them.
Basically, I want 5.7 hemi power without a $30k truck payment, so give me your suggestions. Fire away -

Anybody else have any other suggestions?

Some Cams (Like mine) require the Mopar PCM for recieving the extra air/fuel requirements. 2Wd PCM would work fine.
Just becareful not to sacrifice your low-end, being a 4wd guy, your going to need all the torque you can get.
Why not go with a stroker short-block? Thats the sure-fire way to add instant torque, and everything else added on compliments it.
Then go with some worked heads that focus on low-end flow, stick with the 1.92 intakes. With cams, focus more on the at .050 flow rather then the advertised specs.
Throw in a nice 2200-2500 stall converter with a shift kit.
But just the stroker alone will give you incredible results.
I suggest you contact KRC performance.
Good luck man!
