The updated kit allows for the move to high boost by just removing the restrictor and installing the hondata / intercooler. Without the update you'll have to send in your rotrex, or get the pulley and install that yourself.

The other benefit of the update is that you'll have a powerband that is shifted down in to a much more useful range.

All in all, it's up to you. Since you've already installed the kit I'd just run with it. It probably wont be too much more work to install the new pulley than it will be to rip it apart now and send it in.
