when you change your lower pulley to a #4 how much difference does it make to your gas milage

 

if you have to ask that question you should have bought some jap crap that gets 40 mpg....











jk but it realy depends on how you drive it. My tuner tells me that he sees no difference once you get over the glory of the extra boost.

 

ok thanks

 

Stay out of boost and its the same as before.
