Crazy how fast the power fell. And my TQ and power under peak was down. I swapped back to stock before finishing the tune, much better
Now even at 6600rpm's I am above 360whp...
So, I wouldnt recommend it to anybody. Another member had a similar experience with the rev-up plenum on his 287 FI motor.

I am running an APS Plenum with the 05 lower plenum. Unfortunately my enthusiasm is growing old on this project to see what it will do with the tomei cams and valvetrain under my desk. In theory the shorter runners on the 05 should allow you to make more power at higher rpms.
