Re: tech 2
you can reflash the pcm back to the stock tune for that vin number with it...had to have mine done. and i think you can also adjust the mileage on the odometer as well.
not sure what else, those are the 2 things that stick out in my mind

GM dealerships can use it to reprogram a pcm but only back to stock for that vehicle's VIN. To my knowledge your mileage is not stored in the PCM and is NOT changeable via the Tech2.

Re: tech 2
I HIGHLY doubt that whoever changed their mileage did it with a Tech 2. It's just a scan tool used to monitor and recorded. Dealers upload the info and it goes back into GM for analysis fun.
But changing mileage, that requires more than a scan tool. You wouldn't be thinking of doing something illegal would you?
Right on about how you can change things w/ a tech 2 but as soon as you unplug it, there goes the changes.
Get a laptop to tweek your sensors if that's what your after.

Re: tech 2
It is really only a diagnostic or scan tool.
Any changes made with it (which it can only do a few) go away as sooon as you remove the tool from the car.
