Just ordered a CS with an 87 performance tune for my '06 F150 FX4. Got it mainly to just give my truck a little more juice. I've got 33" Toyo M/Ts and there a little heavier than my stock ones
. So hopefully it will give it a little more go and all that. Hopefully I won't screw up the install or anything. It looks like there is a bunch of ways to screw up the tunes and/or the Gryphon.
