will this work on my 99 3.8 and would it be worht it?

i dont have any mods yet

 

nope, thats for the 04s, go with diablo or SCT to, ive talked to to many people who have had bad expereince with superchips

 

Yes, but I lean more toward the diablo tuner.

 

no it wont, the 04s have different computers which is what that is for

 

what all will a tuner thing do for me? and whats better to get a tuner or a chip?

 

tuner, i would go with a diablo, it will adjust shift firmness and points, along with gear and tire sizes and all kinds of stuff

 

Yeah get the Diablo sport tuner. I made the mistake of ordering the superchips trituner from rpm. And it doesnt work. Why they would only make one for the 3.9 and not the 3.8 I dont know. They claim there was higher demand to make one for the 3.9s than the 3.8s. I had to send it back and get the Diablo. Its worth it. The best thing Ive done to the car so far.

 

SCT Xcal2 from Justin Starkey at www.vmptuning.com

he can load the tuner with more specific tunes that will suit your requests. give him an e-mail

 

If you plan on going forced induction the SCT Xcal2 is the best tuner. Its better for tuning with SCs b/c the diablo requires that you send the tuner to them with your application so they can reprogram it and send it back through mail. Thats taking a chance. When I get an SC I will have to dump the diablo for a SCT because thats what the dyno shop here tunes with. They dont tune with diablo for the reason I mentioned above. Having to send it to them.
