Which Pulley??
*
confused which underdrive pulley is the best? I hear piggyback's aren't worth it but ASP sells a 34% Underdrive which sounds like it should make a difference over a 25% like March.
Are all underdrive pulleys "piggybacks"
By piggyback they mean you retain the stock pulley NOT replace it right?
Are all the underdrive pulleys the same design?
the 23% on ASP's site says it is good for .2 in the quarter over the .1 to .15 for the 34% so I am confused I would think that the 34% would be better than the 23%. I just want the best pulley and dont care about charging.
