My car is a 2003 Auto GT w/ 70mm TB, Plenum, K&N Filter/Silencer Removed and March RAM AIR, SLP LM1's w/ Pypes OR/X and Steeda Pulleys..

Is it in need of a "Custom Tune" or Can I just get a Predator to adjust the timing/shift points?

 

You don't need any of it really. If you're going with a tuner, go with SCT Xcal II. Predators are worthless. If you want to adjust shift points, buy a B&M Shift Kit.

 

predators are not worthless, depends on what your local tuner uses... SCT and Diablo do the exact same thing, but get a handheld, more useful, and hold mulitple dyno tunes

 

Do you guys think that a chip or tuner would actually contribute to my mods? I would gain a lot more from other things I think.

 

tuner helps... dyno tune is best of course but im on a canned tune till I add FI...

 

a handheld tuner will fix the prob. of runnin rich due to your o/r midpipe. itll give you a few options that will give you about 5-10hp. ive had both diablo and sct. personally theyre both the same. just different technology, and really find out what you local shop has and stick with there software. itll save you money in the longrun.

dont expect much from the tuner though.

 

So because I have an offroad pipe, I can lean it out 1 setting or so?

 

no you just trick the computer into thinkin you have cats so it doesnt run rich. itll save you some gas

 

I already have o2 sims though.
