Perhaps the boost level is set too high from the factory... poor ol' CVT
Haha you won’t hear me complaining! I actually reckon it has come down from 1.57 to 1.51 over the last 2000kms... just went for a run then and went passenger and as Leigh said, it max pulls 1.51 and then bounces around between 1.3/1.4...
Max I’ve got is 1.36 and that’s launching and everything! I’ve only done 1,800 k’s though so maybe it will get higher after I do more k’s???
Due to how the factory tuned the levorg, my suggestion is to aim for 85-95km/p/hr to find the maximum boost pressure.
There is a slightly higher value than this to be found somehow and somewhere... be careful on that little turbo
!.52 max here
The differences would most likely be related to local barometric pressure differences.
The boost pressure is controlled by the ecu varying duty cycle of wastegate control valve, this is set by the factory software tables for boost control valve in the ecu.
Slight response differences in these boost control valves could also vary max boost amount slightly.
