Also, can I get you to fill out your userCP more fully? Only us mods can see the information and it would be rather helpful.

Haven't had a chance to try the level 1 tune, ill give it a shot tomorrow when I get back to my truck. Left it when I went out of town and left the keys at my parents. Got back to mine and have my spares so ill check it out when I start up tomorrow.

userCP?
Not sure what that is but maybe this will help:
2008 fx4 screw w/5.4 and 3.73 gears and 34700 miles
35" tires (but keep in mind it only shifts hard on the tune, not stock file)
OBX Longtube headers w/resonators and true dual exhaust
2010 efans
Gryphon on canned tunes
