RushingSlow,
Welcome. Increasing air into the engine and exhaust out always helps. There is a whole school of those that favor tuners; 5 Star is very popular. Also popular is the pedal commander that greatly increases throttle modulation.
I would also advise you to check fuse 27...it's a small yellow 20 amp fuse. Pull it out and look for any brown discoloration from excess heat. It seems that the fuel pump hot wire draws enough amps to heat the fuse/power control box that it may melt even tough the fuse doesn't blow. If discolored there is an easy $12.00 fix from Ford. ( I bought mine from Tasca Ford Parts in Rhode Island). Basically you take the wire from #27 and rewire it into fuse 70 slot in the power control box.
The 13's have a stronger frame than the earlier Raptors and there is less of a problem of frame bending. If you plan on doing a lot of hooning I would recommend getting one of the frame reinforcing kits...RPG, Icon, SVC and others have good kits the have air bumps to greatly lessen the possibility of frame damage.
Lighting improvements are very popular. Baja Designs, Rigid, and KC are all made in USA. PIAA, Hella, and a whole host of others give you many possibilities. Tonneau covers, bed rack systems, VHF/UHF radios, onboard air...compressor or CO2 tanks, winches, traction mats, stereo upgrades...the list is endless..Then the improvement of suspension...better shocks, springs, upper A arms, stronger spindles, Power steering improvements....super charger vs twin turbos.........and on and on and on.....
Once bitten the need for speed progresses!
