finally went to dyno today here are the results after the installation of RMW cam and ALTA 15% pulley..have in mind that GP have allready a smaller pulley from factory.some says 11% some others 13%.so i think the pulley didnt have lots to give me.only a little faster SC spinning.

Nice gain ,I think with RMW tune you will gain 15-20 HP. BTW did you check the Air/fuel ratio?
