For max power head porting is a MUST!! There are big benefits to higher flowing exaust port. And yes. Ported Intake ports are less of a gain on a blower car versus natural aspirated but gains are still there

With a 2.55 upper and 10% overdrive balancer (8.6 lower?) listed in the mods list, I would guess 14psi. Other things that affect the boost have been done to the car though like the CAI, cam, exhaust, etc.

I could be wrong, but I think Josh does the tuning at LMR...

Actually its the bi-polar opposite. You will see exponential increases with ported heads on a FI over NA. For every 15psi of boost you're increasing the volume by 1 atmosphere for the same given capacity. So even a fraction of an inch increase is surface area (flow volume) will have an exponential increase over how an NA engine can flow the same volume. The higher the boost the more exponential increase you will see.

14.7 lbs of boost is one atmosphere, not 1 lb of boost.
