the boost valve just fools the wastegate, if u really want to get more boost use an air pressure regulator as the wastegate and set it at 32psi

well that wouldn't work for him since he doesn't have a fixed turbo it is a VVT so a controller or a tune that sets the boost higher is the only way

well DUH the VVT doesn't have a wastegate, it just used vaine position to controll boost.

Since PPE has set boost in the tune it self u really cant change it around like efi, But the boost controller can go it.

on a load dyno, I gained 15hp and 30 lb/ft torque on top and as much as 90 lb/ft torque increase down at the lower RPMs Real world, high weigh and wind drag towing, my EGT's were down about 100* and my ECTs down 5* overall Not to mention, the trans didn't down shift as much and everything just seemed 'easier' when towing.
I'm keeping my eye on you. I like the sound of those headers. we'll have to see how they hold up for ya.
