I put a number 11 plate in a buddies truck the other day, so in return i kept his stock and had it ground down by my father in law who owns a machine shop to a number 0. The difference is unbelieveble on how much more power. I now need to send my hx40 that is sitting on the work bench to Piers and get him to balance it. Back to the story. If you have a stock plate laying around ground it down and toy with it. You will be impressed. Later on
