underdrive pulleys

u will...hopefully this damn storm will pass quick enough in my area...there are flash floods!!
 
ok well i got the price for the dyno- its $90 for the setup and first run and $15 for any after that. now that is if i want A/F ratio. it $75 if i dont do A/F.


is it worth to do A/F?? i already know its s*** on the Mazdas.
 
well if you find out where in the rpm band it is s*** then you will know where to adjust it. A proper a/f probobly makes more of a diff than your intake, fart cannon and udp, id get a afc before any other mods.
