Tuner/Calibrator

I hunted around for info on the Superchips products and havent found the answers I have been hunting for. Has anybody had good luck or bad luck with either of the Superchips Trail Cal or Trail Dash.
Also, im part of a Jeep family so a question i have is can you use one tuner on more than one Jeep or does it need to be dedicated to a single Jeep.
Love to hear others input on the whole idea of tumers/calibrators.

I use the Flashpaq, not the Trail Dash, so someone else will have to answer that, but each unit does lock itself to a VIN once you've used it. The only way to transfer to another Jeep is to return the first to stock.

That makes sence, i have two jeeps that need speedo calibrated, so ill have to buy two units..... Thanks for info, much appreciated.

I have the Flashpaq as well, which has been great. I love the 87 tune on it! It was actually noticeable and not just BS. Having said that, the Traildash has some nice bells and whistles on it that would be nice if I had to do it over again.
