This is the tune I made for my truck... What do you guys think? It runs good but I'm always lookin for more!! And I also LOST fuel mileage so please check if I did something wrong.
Oh and I'm having a little trouble with the idle... It almost dies every thime I put it in gear or when the a/c compressor kicks on. It started this when I cut my cats out, could this be from exhaust leaks? I didn't think so because I unplugged the rear o2's and my leaks would be after my front o2's. I'll also post my stock tune as well so you can compare.

And my other question is where is the pin I have to use on the pcm for the e-fan? And do I just run a wire from there to the relay to kick it on?

 

33 and 42 are the pins for the fans, 33 low, 42 high.

They are grounded when turned on, but yes, to the relay.

 

Increase your idle speed 50-100 rpm when the ac engages. Disable B701 Cat Protection. Are you logging any huge + or - fuel trims. Thats where you'll need to start looking for your mileage problems.
