I just bought a ss S/C yellow. on a monday and then I had to bring it back on wed. because if I would give it more that half throttle it would bogg out one me and the boost gauge would read at 20psi. But there was no 20psi going through that blower, cause All I was doing was slowing down. Dealer says that it is the Cat.....but come on now. Any one else had this?
