Ok,finally got my Mustang back from the shop where I was getting all my suspension goodies put on. Had my head ported and polished at the same time. But the question I have today is: What is better? To shoot for more timing advance without detonation or less advance but more boost? I was running at 12 degrees BTDC advance with 9 lbs boost and was barely detonating. I backed the advance down to 10 degress BTDC and and was able to run 10 lbs boost with no detonation. So which is the better setup? Can I go to 8 degrees BTDC and run 12 lbs boost? Would this do me any good? Is'nt more boost better?
