Exactly what can u do with the LT1 edit?? My brother has a new lap-top so other then that what all do I have to buy and where should i look to find it?? Thanks, Dustin.

 

I would instead recommend tunercat.com cheaper, not VIN locked does at least as much and in my experiance better service.
You then need a cable from someone like akmcables.com who can also sell you a registration number for an awesomew datalogger http://www.ttspowersystems.com/diagnostic.htm

After that is is a whole lot of learning.
Any time you reflash a pcm you take a chance of having it lockup, with LT1 Edit you would have to buy an addon license for each pcm, with Tunercat you can just get a spare and not worry about having it registered. I highly recommend having a spare pcm it is a whole lot easier than having a dead car should something happen and the pcm in the car freeze up.
