What Leading and Trailing numbers do you see w/ Peek Hold?

This is a bit of a survey.

1) When you use peek hold on the monitor, what numbers do you see for leading and trailing timing?

2) What major mods do you have (engine poring level, boost you are running at, etc.)

3) Roughly where in your maps do you think this peak was generated?

I have a seperate question - but have to admit that I don't have my car (or PFC) right now, and have to dig out the PFC manual to check this (it may be right there) - so if you feal like humoring me - What do the numbers in peak hold mean in ralation to actual timing offset.

thanks,
-Erik

I ran a ***** to the wall run in 2nd and 3rd. Here is what my peek values said

Ign Leading & Trailing: 52 degrees
boost: .92 kg/cm^2
Inj Duty: 90.1%
RPM:8152
Wtr temp 95 deg
air tmp: 65 deg.

I am using the apex base maps for fuel and timing. or cewrx7r1's base-mod map.

Thanks! That makes me feal better - Since I was seeing hight advance nubers like that too.

Now can anyone explain what these numbers mean? 52 degrees in advance of what? Also if there are any basic rules of tuning (when to increase and decrese advance on the leading and trailing) it would be great to hear them. I heard that the single turbo forum has some threads on this... off to check those out.
