Already double stock value and half the activation point. Had to ramp up the settings quite a bit to keep it from knocking on 91 octane with 11:1 static and 9.6:1 dynamic. It still lean cruises at 16.5:1 and 44° of timing at 2,200 rpm at 70 mph. 19.7 MPG on a 200 mile road trip. It loafs along lazily at 52 kpa manifold pressure on flat road. Lots of low-speed torque.

Intake is in my hands. Shipped quick, arrived quick, decent quality and came with install hardware. A little port match and sanding roll cleanup is all I intend to do on my sub 6,500 rpm 383.
