2007 Tahoe Tune
Ok guys just bought my wife a 2007 Tahoe with a 5.3l. I went in and turned off the AFM due conflicting opinions on it, I wanted to see for myself. Anyways, now that its licensed does anyone have any good tips or ideas on things to do in the tune to make it run better or get better mileage?
Thanks Guys!

2005 duramax LLY, 12.75 on stock motor/fuel, 68mm vgt built trans.
Built motor by me, built trans, EFIlive by me, dual fuelers, 80% injectors.
Anyone have any ideas?
Ok so with my wife driving with AFM turned off her mileage went from 15.5 to 13.5 in the city. Those numbers are from do it by hand and also from what the truck says. A couple a tanks later I turned the AFM back on along with updating some of the timing and load tables, the truck is back to 15.5 in the city and got 19.5 at 75mph on a 400 mile trip. Just thought I would share what I found.
