If i was to go with twins or a larger than stock turbo what would yall recomend? Would it help me or hurt me with my 4:10's. I do mostly empty driving however i do pull stock trailers with horses and cows and a dovetail with tractor or roundbales. I want power but my 4:10 restricts my speed. So i dont know if that would be good or not. What other mods would i need to hold up with twins or a bigger turbo?

 

you have no fuel mods so why would you need more air?
