jlt,powerfull great cai, sctx3 its pretty much the standard for dyno guys and tunes, and get the combo from tillmans and i`ll tell you why. tillman is a site sponsor. thats huge in my book. and the price is right. your gonna give someone the cash for the tuner, give it to a sponsor. then you can order a tune from bama any time. the 3 you get from tillman will run great too, so get a 87-89 performance, a high octane performance, and a race tune. ive got a bama race tune also, and i`d buy one from brenspeed, but i dont think they cater much to the v6`s. i`m still running tillmans. (now, if bama chips would step up to the plate, that would be a different story)
