Well you have killed your power by using those large tires, instead of boosting the engine and shortening its life I would lower the gear ratio in the rear end, that will give you more low end power and torque.

tennisshoes is spot on - gear swap makes a lot more sense even though it has less "cool factor"

I'm running stock gears in my truck. Are there any recommendations for a gearing I should switch too to achieve the more torque etc I'm looking for?? Also is it best to keep the limited slip or change to a posi???

You need to find out what gears you have as Ford tends to use a couple of them. 3.54 is a good set for all around, 3.73 are good for more out of the hole torque, but if you want really hard pulling then go with 4.10, or even lower. Remember with each gear change lower you top speed will also drop. Keep the limited slip that way when turning a corner you won't be sliding a tire.
