I guess a lot of it is what you are used to. We've programmed thousands of late model GM cars with HP Tuners since 2003 and have always had great results. Our 8 second FWD Grand Prix, 8 second RWD firebird, 10 second Bonneville, and 10 second G8 were all tuned with HP Tuners.
We offer a package deal which includes HP Tuners and our standard base tune for $599.99 details of which can be found at
