Looks to me like it only does its thing when plugged into the OBD port.  Web site said you go back to the stock tune by simply unplugging it.  I'd think that it wouldn't matter how many times it was used.  Should probably double-check that there isn't a limit as to how many times it can be unplugged and replugged.

Okay but the same does not apply to handhelds though does it? I know about alot of engine mods but i have usually worked on pre-computerized stuff so idk much about the computers and all.

I actually already have all of that different, 20 inch wheels, dual exhaust and k&n intake. Thats why i was asking opinions. haha. I really want to get some more power but i want to find one that is truly worth the money and will not murder my mileage.

Making adjustments with my predator after installing efans on my '04 I could get 19.5mpg highway out of it running between 70-75mph on fairly flat ground. Mine's a 4x4 also. There's lots of parameters you can set with a Predator instead of settling for one tune. There's preloaded or "canned" performance tunes and you can even modify them to your liking a little more.

Now that one would seem worth it to me, haha. I am getting 16.2 mpg right now with mine.

We just got back from a trip with the wife's '05 4x4 and it got 17.2 with nothing more than a drop in spectre air filter in it. It's got heavier than stock tires on it so that might have contributed to the lower than expected mpg on hers. Mine now has a 3" lift and bigger wheels and tires and I haven't hit 15mpg yet with it since the mods have been done to it.

Well i dont guess i am doing too bad right now with mileage then. Mine used to be a daily driver but isnt now so i can tolerate doing some more upgrades now.

The handhelds generally flash their program out, after reading in what is in the vehicle already.  They cannot be used on another vehicle unless the process is reversed - the program that was previously read is flashed back out over the non-stock tune flash.
