For the price of new trucks these days, they should do free oil changes for life. Just my opinion...

My truck: Filled up with fuel and like always, calculated the fuel mileage because that's just how I am. Not that I really care that it's crappy, just trying to figure out why I lost MPG with all my upgrades. When the truck was stock or even with just exhaust and tunes it got about 2 MPG better than it does now after about a year with the intake, EGR delete, lift pump, Suncoast trans, and built trans tunes. All of my previous trucks and everyone else I talk to seems to gain MPG after basic bolt on mods. I can't imagine that the trans or built trans tunes could make me lose 2 MPG but who knows, I might try to load the other ones back in and run it awhile. And before anyone says it's my right foot, it isn't lol. I drive the same as I did before the upgrades, if not slower because I don't wanna break sh!t... thoughts..??

Bought a new fass regulator so my lift pump pressure stays steady instead of bouncing back and forth. The new style removes the standard check ball and replaces it. Also bought new style 194 side marker (red and Amber) bulbs from diode dynamics. Bought the hp5's to replace my hp3's. Should be nice and bright now.
