My buddy MADDOG hit 80 psi today on a test drive with his 12v twice turboed Cummins powered "95 cc 4x4 Ford. I think he is going to have more then enough to cover his old performance level with the PSD as well as the competition still runnin' PSD power. We plan to install some race injectors to see where the motor is regarding power. He is really impressed in the performance. BIG TORQUE! He said he did a 45 to 100 mph run and the impression of his butt is still visible in the drivers seat : )
