MPG Help?
I recently picked up a 97 Chevy z71 with the 350 in it. It has 220,000 and runs great. Only problem I have with it is I'm only getting 11mpg. Could any one tell me how to get it better. I don't have a heavy foot much so I'm already paying attention to my driving.

It is a truck so don't expect too much better but I'd say go get a custom tune and that should help out about 2-3 mpg with you not drivin like a bat out of hell

14 mpg stock would be on stock rims and tires...your pic shows bigger rims and tires and possibly a true dual exhaust. Both effect mpg, and no with a custom tune you wouldn't need a new one, they reprogram the one you have

It doesn't have the same scavengin affect that a single exhaust does...you can add a x-pipe in there to balance that out and it would help out a little more in airflow. Blackbearperformance.com, gowheatley.com, or any dyno shop around you that can tune a truck. Blackbear and Wheatley are just the 2 big ones in the chevy truck world
