What exactly do they do?
with chevy trucks, tahoes, suburbans from '96 up would be interested in getting your truck "tuned"? cost is around $250 and it really opens up the vehicle. i'm trying to get this one tuner to come down here while they're in TX. they have planned visits to dallas and houston. i just checked the site and found that the vehicle applications include cars as well.
Applicable GM Vehicles
* 96+ Trucks, Vans and SUVs
* 99-04 LS1/LS6 equipped vehicles (F-Bodies, Corvettes, GTOs, etc)
* 05+ LS2 based vehicles (Trailblazer SS, Corvettes, GTOs, etc)
* We will be adding more vehicles as time allows!
They pretty much reflash the computer.

For that much I'd probably rather buy a tuner that enables me to make changes if and when necessary. For example switching between regular and premium fuel, or removing the programming entirely for warranty work.
I don't know what kind of tuner you're going to buy for 250....they're usually in the 400 range and are not specific to YOUR vehicle. this one is for your vehicle, how it performs and how you drive it and includes another PCM so that you keep your original stock one for warranty work.
