Hey im looking to see what some people have on their 5.4's. I so far have a cold air intake with k&n filter and a flowmaster muffler that spreads into duals. I like the bigger tired (285/75r) but they take away my acceleration and gas milage. right now i have decent tired (BFGOODRICH all terrian ko's) but i want to further the performance with out my wallet. i am a poor college kid and wondering what kind and what brand seem to help out my triton. I have 2000 f-150 so any help would be great!!! thanks guys!
