coments on tune
logs look good...

In order to determine if timing is being pulled or not, you'd have to know either how much timing is requested in the maps or cylinder individual retard from knock control. Neither being present in the logs, I doubt one could say the tune pulls timing like you do. The values I see seem normal to me, but then on MoTec you're probably used to run 17 degrees on full boost in the midrange, just nevermind the guy who uses an arc welder in the engine bay

It could have been pulling timing oe IAT was different, or coolant temp, or rate at which the throttle pedal was moved, etc, etc, etc. As the other poster stated, you cant just look at variations of timing logs and assume timing is being pulled. You need real time data showing this to draw that concussion.
Me three. A tutorial on how to read these charts and what it means would be a geat addition to our knowledge base section if any of you experts are up to the challenge.
Quick run down...
Time - Time is obviously a measure of amount of time since start of log
RPM - RPM is corrected (filtered) engine rpm. This should match the tach in the dash very closely.
Engine load - A calculation of airflow and rpm... there's way more to it then that, but its basically the main look up when referencing stored tuning data. 100% is basically a calculation of 100% of cylinder volume being filled with air.
Mass air flow (HFM) - Reading of air flow. This will be actual airflow on stock cars, but may not be accurate on tuned cars.
Ignition angle - Angle at which spark plug fires. Important for proper combustion for max power with out knock.
Oxygen sensing, bank 1 Lambda Value - Lambda reading in front of the cat. Rough air fuel calculation is lambda*14.7 = af
Oxygen sensing, bank 2 Lambda Value
Boost pressure of sensor - actual boost pressure in mbar. To convert to bar : (Boost pressure - ambient pressure)/1000 = Bar
Setpoint boost pressure - requested boost in mbar.

Sorry for the late reply, The car puls great and is running as it should so the next step will be to see if we can get some more boost +0.1-0.2 we will prob. Need more fuel
