Posted this over at "the other guys" too but to no avail yet. Anyone help?! I have a stock 2007 M8 and have been looking at doing a "timing key" on it. I haven't been able to track down what degree of key I should be getting. I've heard anywhere from 1.5 degree to 2.5 degree. What have other people put in and how have they been working? Please post and advise. Thanks a lot!
