Well the truck is running alot better. I reworked the tune mainly focusing on the main spark and the shifting tables. I started with a LS2 spark table as the base then tweeked it from there. Truck runs strong for 104* temps. Still debating on the cam swap, it is just tooooooo damn hot to mess with the truck right now.

Ya. Tuning it was weird thou.
Stock heads and 3.0 exhaust liked more part throttle timing
Stock heads and 3.5 exhaust really liked alot of part throttle timing
New heads and 3.5 exhaust hated alot of part throttle timing. I had to lower it 3-4* and it really ran strong
WOT timing roughly remained the same.
