Ok, I am now running at 7.5lbs of boost, and my car was dynoed. It has 360 at the rear, and 306 of torque. That translates to about 450hp at the crank. A stock GS400 has 243 at the rear (300hp at 23% correction). Here is my little web site on my car: http://www.angelfire.com/amiga/supergs400/superlexus.htm Up
