Talking best "free" HorsePower or MPG mods


What are the best Free HorsePower mods for the 7.3l? - I bought a superchip and had it programed for the 80hp setting. it ended up costing me 45$ for the chip and the program was free....

I'm just wondering what some of you have done for cheap and easy HP and MPG mods..

thanks guys

2000 F250 7.3l, took off all engine mods, and lift kit.
