I recently purchased my first truck back in January, I got a 2012 Ecoboost XLT, 3.55 locking rear axle, chrome package. for a good deal so i couldnt pass it up. Love the thing so much. Already did some small stuff, got smoked out headlights, got the SVT tail lights. Swapped the grill to an Fx4 instead of the standard chrome. Put in the 8K hids Plans to come
-4 inch BDS suspension lift, with fox shocks in rear.
-Some 18 inch Anthem wheels
-make a nice touch screen set up on the interior
-Intake
-Possible exhaust
-Livernois Tuner
-Lower boost grill
-Black and red badges
-42 inch light bar on top
The tires are a toss up im looking for some advice, i want 35s but im worried about the gears i have. im not really looking to re gear my truck. so should i get 33s, or let it be because i am gonna get a tuner for the truck and i heard it helps out.

 

slowly getting pieces of my build together, i finally got my CAI and my sct tuner,

 

I wouldn't be too worried about 35's with the 3.55s. With the tuner you can recalibrate your computer to help with turning them 35's. I would say if you didn't get a tuner you would notice it but the tuner will definitely help.
