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.

If you keep stock or near stock programming you'll only get 23-25 psi, which is just fine for everyday travel and some hotroding. If you want the boost to come on faster down low and keep EGTs in check while doing it, go with high flow headers and up pipes like I have on my truck.
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.
