Congrats on the build! Those are some great numbers on 91 octane.
I'm encouraged to see such a stout combination on this crappy California gas.

I've planned a similar build, care to share some additional info?
- Which heads & Intake?
- Exhaust / You running high-flow cats? 3" pipes?

I'm in Palo Alto. Maybe I'll see you at Santana Row sometime?

Hey Scott... thanks.

The heads and intake are most likely what's keeping the power down a little... they are Stage 1 Ported, LS1 heads from FFHP and a plain old LS1 intake. Due to the air being stuffed, velocity and all that, isn't so important as with NA and there's a post in the FI section now comparing a 402 to 427 w/ I'm sure better flowing top-ends w/ similar results. What's kept me from going w/ the prettier (better heads/intake) stuff right away is knowing that turning up the boost just a tad can make up the difference and the price difference is well... something worth considering.

The exhaust is a different story and the freer the better. I run a 3" mid w/ no cats (gutted) to a Borla stinger catback. Car is still very quiet but open it up and you'd see improved spool.

Since this is a good baseline the plan is to put on some really nice TrickFlow 225's and LS6 intake to really see what she does.
