quick question! please help

we are having a ton of trouble on my buddys 07 classic Silverado.
We put a 2004 6L LQ4 in it, i found a tune and changed all the fuel and spark tables over.

Now its commanding 13.1 AFR at idle. and really rich WOT.
Ive tried to change the PE tables and all the fueling stuff, but its not working. Still commanding 13.1..

Now if i go in the DVT and command 15.5 cruising down the highway his gas mileage goes from 12 to 20mpg..


Also how the heck do you do a Crank Relearn with this new software?
I cant get it to work for the life of me!!

The throttle must be at 0% but with the DBW throttle it stays at 16% idling.


Its throwing a P0300 (misfire) and the converter wont lock after that.
Can anybody? help me?
Ive got more money invested in gas goin to his house, than what he has in the swap. Its getting aggravating.

Can you post the tun file?

Have you tried setting all the misfire tables to 32657 across the board? That usually solves the unlocking problem.

Post up the tune file......
