I've done T4 calibration for both #1 and #2 engines.
T4 gauge has been switched and we have cross-wired the wire harness to check whether we got different results yet still producing the same result.
The bleed valve is working fine. I try to swap the bleed valve from #1 to #2 engine. still, both engines got the same result as before
Engine #1 passes the chart and engine #2 is borderline pass the chart with 83% of TQ and during hot day #2 engine TQ will be somewhere at 81-82 %
No particle separator was fitted on the aircraft.
