Who has the edge box in there F150? And what setting do you use the most?

I use 3-extream most of the time. Even with the 35's on it i still average 12-14 mpg's.. Now even with towing i still use 3. I was using the tow mode(2) And i was getting less Mpg's. What i have done to the truck are as follows.. K&N air filter and intake kit. Throttle body spacer.. Edge box 3-inch flowmaster exhaust from the cat back... And 3-inch lift kit and 35x12.5x35 nitto mud grappler tires... when i pull a trailer there not small trailers either one is a 17ft car trailer with 3-big AC four wheelers on it (take a look) www.eastcoastatvsnorkels.com and the other is a 30ft toy hauler... SO i need my truck to be at it's peek... The rears are 3.73's.

Silver,

You from Pa? if so where? i have the 5.4 in my truck... i as well have the 2.5 leveling kit... I do know my speedo is directly on... Thanks for your responce... i'm from Jersey...

 

well im in central pa but i do know alot of people in jersey .. the reason i know my speedo is off still is beacuase i used my mom truck which is the same as mine but crew cab and with the gps hers is dead on and in my truck it is 5mph slower and the gps is dead on for mph tested it in a few cars

 

I run mine on Level 3 and back off the timing -2 so that I can run regular unleaded.
