I did some autotap scanning on my Hawk last week and did a couple WOT runs. I don't have the numbers here, so I'm going from memory.

Max was 29.5*. Min. was 24*. It varied some (even within the same run), and I only saw 29.5 once. Never saw even -0.1* of knock retard. I was recording Throttle angle %, Spark advance, and knock retard. That look good?

As an amusing note the temperature gauge reached 210* by the time the actual temperature read 180*.

Mods are ASP pulleys, K&N, DirectFlow lid. (I know, not much).
