I have a 4 inch lift and 31x10.5 worn out bfg all terrains but in the past two months I've noticed a loss in power anyone know wht could be causing this and/or how to fix it?

Sea foam might be the cause of your problem. The excessive smoke may have damaged your O2 sensors, causing a wrong air/fuel mixture and causing bad gas Milage and a loss of power.

I read somewhere some fuel cleaning products are bad for some newer fuel lines. Always wondered if Seafoam or any other product like it will damage a 02 sensor? I wonder the same about some of the throttle body cleaners?
