which is better flowmaster 40 or super 40s, and should i get 3:73 gears under drive pulleys throttle body and could someone explain to me what a tuner does
40's are better than super 40's. super 44's sound the best on the 3.8 though. when you get gears get 4.10's, throttle body is a waste of money, and make sure you get 42% u/d pulleys not the 25's
i take it ur not interested in my cat-back anymore? and idk bout flows..but also a tuner depending on ur mods saves u gas with economy tunes..and it brings out that extra hp that u get from ur mods

tuner gives you a new coding on your ecu which tells your car different things that increase performance (air fuel mixtures, higher octane fuels, different tire sizes, different gear ratios, etc) it's good for about 15 to the wheels
oh and if u drive stick get 3.73 auto 4.1 TB like that guy said is usless and yes u/d pullies are good
