5.13's
Cooper STT 37's (36.25" actual)
430ft or so elevation
Airraid CAI
Magnaflow 4"x18" muffler
Superchips programmer on 87 octane
Mostly city style driving
I get 14mpg. I am really gentle on the skinny, no quick starts, hardly ever get over 65mph.
I haven't taken a longer trip on the highway but last 30 mi Interstate drive @ 60mph computer showing 17.4 mpg.
