Edge :

 

The police confiscated the car - And surrender to duty / tax authority :/ If they suspect that the car exceeds 20% of the normal HP

 

they will lay a charge before you can get the car back ...

But is the Wastegate to big ( think its a HKS GT 60 mm ) to drive 5.8 Psi . .. ?

 

I think the wastegate minimum is determined by the spring? I don't think there is a minimum boost due to being a larger size, the bigger the better basically as it can control the boost of larger turbos easier.

 

You can take the wastegate out and change the spring to whatever you want AFAIK.
