I'm thinking that if they have been testing this kit on their developpment cars for over a year and all of them show 8psi of boost on the dyno and on the road, then they sell ten kits and customer #3 says, "hey, I'm getting 10 psi of boost, but making 25 lb/ft of torque less than what you guys advertised," then Stillen would say, "please take your car back to your installer and have them check everything out, something must be installed wrong." Not, "please do not run your car with the pulley we included, it makes more boost than we advertised. Please install this other pulley instead." They were able to trouble shoot this issue and deliver a fix before all of their pre-orders were satisfied. That indicates they knew about this issue very early on. In my particular case, I was an early pre-order (3/16/10). I wasn't informed that I would be getting a resized pulley until after the order was paid in full, the car was in the shop and the install was nearly complete (late june/early July).
