Actually, you don't need computer work unless you're pushing towards 350hp. The stock 5.2 OBD I will accomodate a Magnum RT cam (not the cam from a Dakota RT), headers and free-flowing exhaust and a supercharger running around 8psi. This was done back in the day with the 1992 Dodge Dakota 5.2. Initially, they tried the Mopar Perfoemance aftermarket computer, but it dialed in too much ignition timing for the supercharger, so they went back to the stock computer. Later, with even more gas-hungry mods, they went back to the hotter PCM to get fatter fuel curves and had to put in an in-line timing retard for supercharger applications. First and foremost, you want to get a computer-friendly cam. Keep the gross lift at or below 0.500 inches, keep duration under say around 210 degrees, and keep a wide lobe separation of 112-114 degrees. This will give good flow while limiting overlap. That keeps the manifold vacuum high, and the computer happy.Point being, the stock PCM will handle a lot. One other thing the 5.2 guys would do would be to swap in the 5.9 computer since the pin-outs were the same (on the OBD I's). That gave much fatter fuel curves for the 5.2 to play with if heavily modded.

I finally took pics. Wanted to wash it first, but my spray nozzle is broken. Will post the pics asap.

Well, here's the salt covered beast! My headlights are wired weird (LEDs only come on with high beams), and that's my little brother next to my tire.

So I finally have the money to buy a CAI (just a cheap little spectre - they seam to be worth it at half the price of competitors), and I'm thinking about doing the TB mod. Should I do it? Will it be worth it in the long run?

Looking good dude. You notice any difference with the projector headlights? I'm trying to figure out which style I should go with to get rid of these crappy 2nd gen pieces. And from what I've read on the forums, the TB mod is definitely worth it. I haven't done it myself (not that experienced, personally) but I do want to get it done sometime soon

There is quite a bit of a difference with them, and mine are the stock brightness halos. I might upgrade them. I don't recommend the ones I have, because there wiring is more confusing. I would recommend something like these personally. http://www.ebay.com/itm/94-01-DODGE-...e02cc6&vxp=mtr

Installed my CAI yesterday (December 31)! I'll post pics after I do the TB mod. Might be a while. Bought cutting wheels for my dremel, but it's freezing outside.
