The bottom line is, you gotta pay to play. I know the risks. I also understand that if I break my transmission from running too much power I am not going to GM to fix it. Unfortunately, too many people want to make more power, they break things and then want GM to pay for it. This then forces more and more dealerships to try and void warranty claims. Classic has been great with our Pontiac and given us no issues at all. Moritz is where I take the truck and they've been great too. I will probably start taking the truck and the Camaro to Classic since they have such great reviews here and are much closer to me than Moritz.
I know that within the first two weeks of me getting my Camaro I'll have a tune on it. The G8 jumped about 30HP to the wheels with just a tune. Too much fun to be had with a tune. LOL

The G8 made great gains with a tune because that engine is more detuned than the LS3. The vette's don't gain 30rwhp with just a tune. They usually gain ~25 rwhp with a tune AND a CAI though.
