I did a little fine tuning myself

The car sees 3-4 more inches of vacuum w/ the throttle plate cracked a hair compared to before the header wrap. I'd say the retained heat is helping quite a bit...SO:

I got a little more aggressive with cam timing up top and bumped ign timing ~1-2* from 6400-8000rpm.

Also I felt it was a little zealous down low so I lowered by ~.5* at ~5200rpm.

I did 4-5 pulls and holy cow did it make a difference

Pulls were at wastegate boost of 17psi and feels like a legit 400whp. I might report back with airboy dyno #s
