Hello pals,

Straight to the case:

Currently running stage 3 on my car.
Modifications: Hybrid turbo, FMIC, ceramic clutch, free flow 2.5' exhaust.

Turbo maker says to achieve 220-240 ps i need to boost turbo to 1.65-1.7 BAR.

Chiptuning company where i have my car mapped said that turbo wasnt responding on the pressure request. After they overboosted turbo, it started to push over default, which is 1 BAR. They reached 1.45 BAR and then when they requested more again the turbo did not go higher in pressure. So now running with this pressure 1,45 BAR - 216ps 465nm.

Somewhere i read, that you need to setup N75 valve, but i dont really understand it too much.

Question is, why the turbo pressure wont go higher. They couldnt answer me this, they didnt know it.
MAP sensor is to 2.5 BAR.
Engine is in very good condition.

Thanks for every answer.

Have a good day.

Maybe add a post in "Introduce Yourself" before asking for things ;)
