Ayousef,
Here is another Livernois 429 that makes big #'s on lower boost. Livernois has an awesome engine program, and the CNC port work on our LSX LS7 heads is killer. This customer has yet to upgrade the fuel system or head unit, but he daily drives this car and it has been flawless. we are hoping he'll let us crank it up a bit this winter.
