You realize its my truck rubbing off on yours right?

I think you need better exhaust to make use of what's upstream.

 

Same here, my truck was night/day different with the heads on.

 

same here. gained ~40-45 horse with a head swap and higher comp.

 

Yeah Alex, your truck ran damn good when you put on the heads

 

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.

 

glad you got it running better. mines been shifting weird too, wot it will pause for like 2-3 seconds then slam into gear hard.

 

good to hear. so are you more happy with the heads swap now?


thats not good.

 

I'd do the intake first since you seemed to want to do that so bad and its easier. I just wouldn't want to mess with getting that pulley off

 

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.

 

sounds right. increasing cylinder pressure and hot outside temps will do that. mine is like that to.
