Gas milage?

I was wondering city and highway gas milage people get for 4.3l 4dr. Blazers and jimmys (around 1999) with a 2 inch and 31's. Try to keep engines stock please. Pictures of 4dr. Rigs welcome! =]

In that case I think that I'm going to chip mine and see my milage after that...

They were rated 16/20. Mine averages around 15 mpg unless it's on the interstate 75-80+, where it does a solid 23.5 mpg. Any other time it won't budge past 17 at most. Bone stock '99, btw

That's still not too bad I guess. I might invest in a more expensive fuel chip if I can find one that does its job and is engine efficient to boost my mileage a bit.
