So I keep seeing these things on e-bay and am thinking it has to be a bunch of bull because there is no way this can possibly work and be so simple and cheap but then looking at the sellers feedback there is actually alot of people who are giving very positive feedback. So I am almost tempted to try it out now. What do you guys think?

Although it is total BS, it is total BS for the 1st gen car. No product could claim compatibility for both the 07 and 08. The only people close to development of a performance electronic tuning module are d3. You can check them out at d3cadillac.com.

BTW - The people who are reviewing the product are prob this guys friends. Oldest trick in the ebay book.

just send me the money, i'll buy beer with it

The only thing it can't do is make coffee.

On second thought, send me your WHOLE CAR and $2000 ad I will send it back as the first Supercharged 2008 CTS!
