XKR pulley upgrade
I have a 2006 XKR (X100). Saw a site on ebay selling a pulley upgrade for the supercharger. Claims 20+ hp add through the extra boost.
Anyone with any experience with a pulley change? I had a Mustang Cobra with a pulley change and it was a real benefit to HP.
Does it need to be re-flashed? Or is it "plug and play"?

Yours being 2006 would already have a larger diameter crank pulley than the 4.0 litre models so you may just be left with the smaller blower pulley as an option.
No reflash, it is my understanding this is not possible.
