I dropped the truck at the dyno. pre-dyno compression test went well. First dyno pull the coilpacs start acting up, can't build rpm under the load. Off the dyno and replaced, back on and the truck runs a little lean and fuel pressure drops. Off the dyno and change the pumps.

finally dyno'd and tuned. 488.5 hp and 557 torque. Done on an axle dyno. moderatly aggressive tune, with 14.74 pounds of boost. Still room to spin that Magnum Powers faster.

built block , magnum powers, crowler cams, kooks long tube and the other usualstuff.

pretty happy about the results.
