can also do better fluids in engine, trans, t-case, and rearend. you can actually get a few extra hp and tq to the ground doin that and pick up between 1-3 mpg.. not sure how your CAI is but if you have a pipe drawing the fresh air from below the bumper, then you should pick up a a little performance (just remember to disconnect it before ya go muddin)..less restriction on the fuel system, check all your filters and connection points. personally i dont like quick connect fittings, i believe it adds a restriction point in the fuel system, so i always cut em out, flare the ends, and go the route of AN/pressure fittings.. do a flush and fill on your coolant system..you can also port and polish your intake horn or whatever it is they use on ford and you exhaust manifold too, if your brave enough to tackle it you could polish your exhaust housing on your turbo too. if you do it i would just stay a few millimeters away from the edges of the wheel housing, just to make sure ya dont slip and damage anything....there are a ton of things ya can do for a couple extra hp/tq here and there and they are normally the most commonly over looked things
