NOVA Dyno numbers today
I milled the heads off -.020 and used the GM gaskets. Im at about 10.85:1 compression.
My AFR was crazy under load. It dropped to 10 ish and go up to about 10.75. So I know there is room for improvement. I uploaded another tune, and the AFR was 14.50 then dropped to about 10.00 and also leveled out at 10.75.
My goal was 420 RWHP when I had stock 3.43 rear. 425 RWHP through 3.90s was a pleasent surprise.

Here's a couple links to my dyno runs. One is the dyno numbers and the other is the Air Fuel ratio. The AFR was a tail pipe reads

The red and blue lines are the first tune, and it drops down to 10.00 AFR as soon as there is load.
The green and black lines are another tune I up loaded for SD, and it went real rich and dropped to 10.75
Looks like the car has more work on the tuning side.

Phil, if you're just trying to level out the A/F at WOT just use the PE table. bring it up in HPT and look at your graph and add or subtract in the areas that require either.
