Has anyone installed the Stage 2 Cobb tuning Power package?? Is it really worth 18-20% increase? Also, How is Cobb tuning's piggyback ECU?? Thanks

I bought the stage 1 kit, and it's not too bad. I'm still waiting for half of it, but I did get the muffler and pully on and the difference (by the butt dyno) is noticeable, but not phenominal... I figure it will be pretty good once I get the mid-pipe and the K&N in.

I've heard bad things about the borla headers though. And the ECU for the MY00 isn't ready yet.
