The stock pulley was 20% smaller. I guess theory you might be acclerating wear on it, but I highly doubt you'd ever notice a difference in wear. Mine has been on there for at least 5 years now, never had a problem or had to replace it. I bought it at the local parts store,with a lifetime warranty.
I would definitely change the pulleys, might as well gain everything you can for the 5 seconds it'll take you to swap pulleys.
