I have done some looking and everyone says guages first. Im no sure how deep i wanna go with engine mods but i plan on 4" exhaust, intake and tony wildman chip! i dont plan on doing any racing or dragging or anything like that i just want some more power. i really dont even pull much. A small trailer and a boat once in a while. is it really necesary to still install gauges? Just trying to get an opinion from everyone.
