I picked up a couple MPG city / hwy . Not sure if that's because it's so much louder I try not to be too obnoxious or whether its just better flow so less work for the engine. You decide =p

My Gas milage got better by about 2 mpg.

Went back down with the 4.10's.

Cam had no effect.

Honestly, my mpg stayed around the same. I went from 20.xxx to 21. Thats all city driving, but the gain gas mileage wise was minimal.

rear o2's have no effect on engine management

According to my spreadsheet:

Before: 17.89 MPG

After: 19.31 MPG

These are averages including all trips city (when I say city, I mean city...stopping for about 2 minutes every 500 feet you drive which is 75% of the time I spend in the car every day) and highway. I do not have a tune...
