I get about 18-20 combined. I accelerate from a stop faster than most and try top speed runs every now and then. I have a complete exhaust, an intake, and a lot of extra weight in the trunk. I think it's doing alright, but would like for it to be in the mid 20's combined.

 

95 w/ 119k and I get about 17/18 on 17" rims and 225/50/17 tires
