Below are the readings i've got on 1 occasion:
Oil temp = 79
Water temp = 83
Exhaust temp = 600
Imjector duty at peak = 88% (full boost, 2nd gear)
what peak boost you get = 1.2 (max reading on my display)
also
what does your dash oil pressure read when you boost hard. I think the scale is 0-8 x 100 kPa: on idle is 2, full boost 6
and when cold it does have higher pressure, also higher rpms aswell.
