a) no swearing :-p

b) I think I'm one of (5?) guys with 'big' tires on here. I can still spin em A tune is a real good mod for the $, I have a nelson tune, did wonders for the truck. Intakes, underdrive pulleys, electric fan conversions, all help with power, and can be had relatively cheap. For more money, gears are best way to help performance. Then you get into cam/heads/nitrous/turbo/etc lol.
