Well I'm new to the club, but here's my list. Gonna get some before and after pics, sorry none right now as I am currently in Iraq. But i have a bunch of stuff piled up waiting to be installed at end of Aug. when i get home.
Already have K&N cold air and true duals exhaust.

-3" body lift = at house awaiting install

-Torsion bar keys to level out the front = at house awaiting install

-XD series 797 spy rims = at house awaiting install

-Larger tires- buying upon return home to get a test fit before buying

-Diablosport Predator computer tuner= at house awaiting install

-100HP dry shot nitrous- any suggestions?

-Sail panel LED's

-Super charger kit- someday, when i have about $5k just laying around

-Backup camera

-New exaust tips, mine are kinda funky looking but not complaining, came   with duals when i bought the truck

-backlit logo panel in top cubby hole

just wondering if anyone has suggestions on tire size? i've got the leveling kit and body lift going on. im looking at some Maxxis Bighorn M/t in 305/70/17 anyone see any issues other than some trimming of inner fenders up front. anyone have a good place to get tires? i like H&H tire in fountain they seem to get me the best deal last couple times i got tires, they quoted me $177 ea for the Maxxis which isnt bad for 34" M/t, other question, what kind of backspacing and offset is anyone running with aftermarket rims? hope i didn't goof with the ones i bought.
