I was wondering if I could get some info on pulley kits.
There are two companies offering pulley kits for $999, one includes a tune, and the other one does not.
The one company that includes a tune has the option for a 181mm or a 185mm pulley, and the other company only offers is a 178mm pulley.
One seems more popular than the other(the 178mm pulley is more popular), and I am not sure which one to go with.
I have to say, the one company offering the tune with their kit seem like a better deal.
Any help would be much appreciated

Thank you
Rick
