John, it's well worth the few hundred bucks to have somebody tune over the phone/internet. Couple-three hours you're done. If the tuner has a lot of experience, that's a piece of mind. Blown up a few thought I could do. It is soooo easy to do, one minor mis-calculation...... oh well, pull engine, start over. Get sick of that scenario after a while. :burnout: Add to that the occasional bad gas scenario, just magnifies the "mis-tune" problem. Before you know it, you have some other issues that pop up and chase your tail trying to find an issue that should have never been there cuz you thought you could tune it yourself.................
Just words of wisdom here. I can build it, take it apart, transform it, but leave the tuning to the experts. That's their specialty. :glasses7:
