btw paul i didnt mention that im running the stock axle back but with a qtp exhoust cut out. when the cut out is open i get 1psi more, idk why i didnt think about it. so with the valve open i get 8psi. i dont normally open it up while in boost (on the street) unless im at the track, just way too damn loud...hahaha

^^ open it up ftw! you get an extra psi since the turbine spins more freely with less back pressure, that means more job on the wastegate to dump.. got it figured out yet?
