Question 2011 LML Low MPG

Got a fairly stock 2011 LML, 87k miles, FASS 165 LP, S&B air intake, sinister intake bridge, and running 33's @ 70psi on a 2" front-end leveling kit. I commute daily to work which is a combination of town and highway. Changed my stock fuel filter and installed the FASS at 84k. NOT deleted. Currently only averaging 11.4 MPG (dic) and about the same on my Edge CST2. Seems to regen in spurts 1-2 times per fill up. Any thoughts, ideas or suggestions??? Thanks!

Default

Run some tanks and hand calculate first then report back. The DIC can be way off

How many miles do you typically get on a full tank?
