Hello everyone. I have been using this form for all my Diablo Predator help for a long time but finally want more out of it. First off. I have a 99 Silverado (NBS) 1500 4.8L 4wd. Mods include: Cold Air Intake. Dual Exhaust (Y pipe were I cut muffler) 285/75/16 tires. Torsion bars rised to help level out front. Rebuild front Diff. Rebuild Transfer Case. Rebuild Tranny (with Vette Servo) Brush Guard. Roll Bar with KC Daylighters. So i have been using the Canned 87 Octane Tune but tweeked it a little. Adjusted for tires, park and drive idle raised 200rpm.
I love the tune! My buddys cant believe my truck is only a 4.8L with how hard it goes. But what I am wondering is what else should I adjust to get the most out of it?? I wanna get a Lew Tune but am waiting till I can afford the Trinity and tune package. (want Trinity for Tranny support) Any advice is welcome, and thanks to any who help!!!
