Wanted to get on here and introduce myself. I recently graduated from Oklahoma State and told myself if I survived engineering school and got a good job I'd go buy the truck I always wanted, so here I am! Bought a 2011 F250 Lariat FX4 4 door. Absolutely love the truck and am beginning to put a few of my own touches on it. Really want to program it and delete the DPF and Cat. Of course I'm reading threads on this subject but would appreciate anyone's $.02!! Thanks in advance!
