I have been playing with the Preditor that was sent as a sample, I installed a Volant air intake and Corsa exhaust and with the Preditor it made a big difference, I am planning to get the Escalade back on the dyno, we did a before dyno run and want to do another run to see the difference the mods and the tuner made, the problem is I can not use a normal dyno I need the 4 wheel dyno and the place that has it is a pain to get an appointment with, and I would like cooler temps so I can get the same conditions as the stock run.
Yeah, I've heard that. I have LT1-Edit for my Fleetwood and LOVE the things it lets me do to my PCM. My wife's Denali has ALWAYS driven me nuts with the piss-poor trans calibration from the factory. I've tried several times to get the dealer to do something about it but they just say it's operating to proper factory specs etc.
