DO IT! it really changes the driving characteristics of the VX, even my finance thinks it rides smoother and faster now too!

I just added the 5 psi pulley and changed out the factory spark plugs with some Bosch Platinum +4.

I really am happy with the way it drives, more grunt off the line and SO much faster on the highways, of course I want more POWER... but you always do.

I really need to meet up with John or someone close by so we can race and really see if it is faster.

Good luck,
Dave
