Ok - Ok - Ok- The dealer will honor my extended gmpp warranty if HE does the WORK. The PCM will be pulled and sent to HIS tuner who will also do the TB. That way the dealer KNOWS he can rely on the tune. The tuner already has my readings from the dealer. The car has a Vortex ram air and Corsa sports already. I'm at 345 rwhp now- I know. 375hp at the crank. c6 auto 2006. THE DEALER SAYS WHEN THE WORK IS DONE I WILL BE AT OR NEAR 370-380 RWHP. IS HE FULL OF IT. I don't think he'll go for a before and after dyno run but that is the sure way of knowing what any increase is. The dealer and I both agree on the 345 rwhp the car has now all we would have to do is dyno it after and see the results. $1200 Tune, TB, and 160 stat. I don't want to say the dealers name but he is Nationally known in racing. Enough said.
Thanks for the additional information as it helps with guesstimating your results. One thing we can agree on on is the 345 starting figure. The ls2 a6 dyno stock approx. 335 rwhp, the Corsa Sports are worth maybe 10 and the Vararam people claim it doesn't show on the dyno so you are around 345 now. In post 21 above I showed ls2 m6 with Corsa Sports, Hallteck cai and tune at 365. Taking away 10 for my tune and 10 for your auto that leaves 345. So to compute your end result add 10 for the tune and 1-5 for the ported t/b, 0 for the stat, looks like 360. I will tell you when I did the Corsa's, Hallteck and tune there was very little change in performance, the car sounded better but there not much SOTP difference. Like siffert said, it's your money and your car. Do what your your heart tells you, enjoy the hell out of your car and let us how it turns out for you. Good luck.
Stop The Presses- Everything is on hold. The dealer will NOT guarantee me 370-380 rwhp after Tb, and tune. He says he just doesn't know. WHAT? That's not what he orrigionally said. I'm thinking to spend $1200 for maybe 10-15 rwhp is NOT worth it. I don't mind spending the money but I would want to get the biggest bang for my buck. As the car stands I have a full gmpp in effect and maybe down the line when it's expiring I can make some serious mods and really KNOW i have serious rwhp. Thanks everyone for your advice and I guess that trip to FL with the family this summer I'll be using that $1200 for some good times.

Thats what the forum is here for, to help other members with thier questions. As you can see, after being tossed around a bit, the forum provided you with a good service. By asking your dealer a few more directed questions the whole story changed. For what you were getting $500.00 would have been plenty. Not worth risking the warranty for 15 hp. For an extra 100 hp with h/c and full exaust now that a whole new question. Good luck and have a nice day.
