I live in California and put a K&N Cold Air Intake and a MagnaFlow exhaust on my 2007 Jeep Grand Charokee Limited 5.7 Hemi. I had just purchased it used and didn't check my mileage before adding the 86 octane tune. Now, with mostly city driving, I only get 9.3 mpg. Should I try putting 91 octane gas in and change the tune to 91 octane? If anyone has had this bad of mileage, I would appreciate any help.
Thanks,
Mark

Id give it some time as the DIC may be off for a bit.
If it doesnt come up, put it back to stock and see what its like...if its low stock there may be a mechanical or tune up issue that needs to be addressed.
