Rog. I have the full AR throttle body set up, ECU, manifold, cat and exhaust conversion. With the 4:1 axle. ( and a few extra goodies)

I'm getting about 163 HP at the wheels. I'll try and post the rolling road dyno print out to show you the much improved torque curve.

I can't, however, fully explain the glorious sound of throttle bodies at 7000rpm!!
