GT Sport TwinCharger Shunting

[Mattlock]

Faults with n75 or n249 dont rely ahow themselves in this tange as the supercharger is before the turbo.

So for my general understanding, the N75 and N249 only govern the turbo?

[piper26]

Basically yes. Obviously its not a simple system. N75 operates the turbo wastgate and n249 is the recirculation valve (on front of turbo) boost under the charger is effectively governed by the changeover valve to increase or decrease the % of air directed through the charger

So the more I drive, the less the shunting appears to be happening...

Which would push me towards the gearbox re-adaptation and the gearbox then having to relearn my driving style...
