OK guys, help a newbie out without being to harsh! I'm looking at doing a pulley swap for some mild extra horse power. Not looking at getting into much at this point. I've read many times that you can add the lightning stock upper, and add 2# of boost, and not have to have a tune. My question is what kind of boost can you have on a stock tune? The lightning uppervmakes 8#. Can you go 10# or is that's much? Thanks in advance for the help!
