new guy here
 

hey there everyone new guy to the site here so im just gonna jump right in. i recently bought a 2010 f-150 lariat from a dealer here in new orleans. right out the gate i put a k and n cold air intake on it thinking maybe it will give some help in the throttle lag im experiencing. well i read a few threads on here about the issue and think i may have wasted my money with the k and n but oh well i got it now so im keeping it. my problem is it seems that the truck is flexing in its calculations of my miles till empty and mpg display on the dash and i think i may be using more fuel even though my mpg has gone up since instillation. im not really super educated on truck modifications or anything just figured this would be a quick slap on no problems piece. from what im hearing i may need a tuner so the truck can refigure the afr its getting now but i have no clue any help would be appreciated before i start messing with anything else. thanks a bunch

Try and disconnect the negative battery cable for 30 min. Should reset the computer, and it will relearn the new settings with the intake.
