here is a link for a good way to do the 10k mod. gains up to around 30hp have been seen on the dyno using this method, but you gotta play with different resistor setups to find what your truck likes the most. also the temps can get warm with this mod so its ok to run it just take it out to tow and don't keep your foot in it toooo long. LoL
tons of pm's on my 10k - Ford Truck Enthusiasts Forums
you can also shim the FPR(fuel pressure regulator), mod the IDM(super duty IDM or upgrade yours to 140v), HPX line(around 30 bucks from tymar), exhaust, guages, shift kit(you can do one yourself. if i can find the post i will post a link. if interested get on ford-trucks and pm coonhunterjoe.), tranny cooler(6.0 tranny cooler or tru cool), the list goes on and on!!!! -
