Safe a/f ratios, no knock, low timing (16 degrees advance), a very safe and monitered tune, almost like you'd see with doctors watching someone in the ICU wing of a hosptial.

16 degrees of timing advance on pump gas and 24-25lbs of boost is nowhere near "low timing" unless you are running a really low compression ratio (in the 7.5:1 range). Don't you guys think timing should have been set in the single digits when running that much boost on pump gas? I could see maybe 11-12 degress but 16 degrees just seems pretty aggressive to me for not using C16 at that boost level.
