Check out this website, if you look thru all the sections you will find all sorts of things you can do to your blaster, tips to maintain it, make it run better, make it handle better.. everything you can dream of.... Theres even a few guys who have been building blasters for many many years and know them inside out and upside down, if you get stumped, they have the answers, but make sure you read first.. the old timers get kind of pissy if you dont do your homework, kind of like your teacher when you get caught cheating on a test instead of studying.
