Predator tuner

[ferg's04Tahoe]

I am considering buying a Granatelli Diablo Predator Tuner and was wondering if anyone else has one or knows if it is worth it. My end result is improved gas mileage. It is for an 04 Tahoe LT 5.3.

I have one you get more power and can adjust about anything you want. As far as mileage not sure, mine hasnt droped but I havent been able to stay off the gas so I gues its better.

Anything??? The end user had minimal options, the handheld makes all the choices for you based on its pre-programmed resources. If you really want to tune yourself, get EFILive or HPTuners.
