1. Install a Cold Air Intake
2. Computer Chip Jet Programmer
3. Install dual exhaust
Has anyone out there tried any of these? Any luck? Thanks!
How many miles are on it? On my 09 I started out averaging 16-17 mpg. With it breaking in around 5-6k, and loosening up I am now up to 18.5-19 mpg avg.
As for the 3 above, the only one that has much of a chance IMO is a CAI, but that is debatable. My experience is that a CAI does nothing but make noise, same with exhaust (which may also decrease mpg as it might cause some loss of low-end torque, in exchange for high-end breathing). That is my experience though. Don't even consider 2.
Might try a drop-in filter like an AFe Pro-Dry S. K&N could also be considered, but it's not my first choice.
For my mpg's, I can always equate what I get to my driving mix (city/highway), style (jack-rabbit vs. a bit easier) and AC usage.
