The dealership SHOULD be able to do the tranny learn for you via plugging it into the computer. If your dealer wants to charge an arm and a leg for it then I say do it yourself. I took me less than an hour to install the S1 and do the quick learn. The only difference between yours and mine is I've got the 04 so I didn't need the injectors, and you will need to have the injectors installed. As far as plugs and wires go, you don't necesarrily NEED them, but to get "optimum performance" out of your PT it's a good thing to do. Pick up some MSD wires from modernperformance.com, I think they're like 44 bucks plus shipping. As for plugs, most guys can get away with regapping the stock plugs to .040-.038 instead of the .052 they come as. Other than that, a nice intake and exhaust package to go with all that and your cruiser will be flyin with the rest of us
