    Cool Whats the best chip or programmer?

    I like the Diablo Predator because after you install there standard tune (87,91 or 93octane) you can than fine tune the engine and tranny. One of the biggest performance increase came when I dialed in the Long Term Fuel Trims (also known as injecter slope) After you make your adjustments you can go to the live data and check for engine knock. There website doesnt show everything you can do with there programmer. Go to there GM forum, its long but you can find all sorts of tuning info. You can adjust the tranny shift firmness and shift quickness. I run the 87 tune and added ignition timing, adjusted the Long Term Fuel Trim, turned off the rear O2s, adjusted tranny to the firmess shifts and quickest shifts, changed tire and gear size and changed my shift points. It takes time to dial in but its worth it.

    Welcome to the site! I've used the "Hypertec" on a '96 I had and it worked well. I have not tried one on my '04, but I'm sure you'll get some more input.

    I use HPTuners. I've only used it to adjust the basics, AFR, Timing, Fuel Trims, Torque Management. There is so much more to it though.
