Can I upgrade the SC pullies on my JCW?

I heard the JCW comes with 13.8% SC pullies, is there anyway I can upgrade to 15% or 17% to get more boost?

Certainly. Just as easy as you can upgrade the pulley on a stock car. The question is, (and I won't be the first one to point it out) why upgrade the pulley (thus void the warrantee on the SC) when the two greatest values of the JCW are the warrantee and the 'refined character'? You risk both of those by changing the pulley. But it's been done before.

Car comes with 2 yr warrantee but I had the car for over 2 years, but my question is which one do you guys prefer, 15 or 17?

pulley replacement JCW

If it were me, I would do the 17% compression type from Helix.
Max boost without limiting RPM range.

Of course, what Chip meant to say was: the 15% is for the Racer, and the 19% is for the conservative driver.
