Blake,
Maybe I'm in a foul mood tonight, so please excuse me, but I am actually offended by your advice because you're putting peoples motors and wallets in jeopardy. Particularly # 2 about pinging. By stating that pinging is nothing to worry about, you have demonstrated that you really don't know what you are talking about and are discrediting this website as a source of good information. I won't even go into your other equally wrong comments with one exception concerning octane and power (# 8 on your list). You will lose power running too much octane for a mildly to moderately modified Mustang (I have the time slips to prove this). Street Mustangs should run at the lowest octane levels possible without encountering ANY detonation, as you will lose power with too much octane, maybe not noticed on the street, but you will see it at the track. A car should never ping, and detonation has the very good chance of destroying your motor, especially if you ignore it and proceed to hammer it while detonating. Mustangs do not have the ability to know what octane is in the car and adjust to generate more or less power and to prevent detonation. I'm hoping you were confusing other cars which do have this capability but Mustangs do not.
