I have 1400 miles on my V6 1LT with JBA shorty headers and MRT V 1.0 exhaust and im getting about 16.5 mpg it is 95% city drive. I only take it out on the weekend to play and I play hard! Ill be hooking up my InJen CAI as soon as it comes... see if it helps at all? Maybe I should drive a little slower from light to light..
