I'll be starting the L92/L76 install tomorrow on my Z51 A6 C6. I'll try to keep everyone posted as to how well it goes and if anyone has questions, please ask and I'll respond to the best of my knowledge. This "swap"of sorts seems to be a very affordable,stock appearing mod promising good HP and TQ across the board. CAM in Durham,NC will be doing the work and tuning and I'll fill you in on gains and drivability issues. Right now I'm at 422 RWHP and 397 RWTQ as it stands with a mild cam, LG headers(with cats),FAST intake and tune. Of course the FAST will be gone witht the install, but i'm hoping for at least 450RWHP and 420RWTQ when the C02 clears.
