Did anyone install these "tuning programmers" for your Escalades and if so, any significant increase in hp / torque?

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.

I'd just love to get one to reprogram my tranny. The shift program SUCKS on my Denali.

With the Preditor you can control shift points and pressures, it does a good job with them. :)

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.
