To get my CA coupe registered the WA Liscense/Transport Department require the vehicle to generate no more than 5 psi of boost.

Im jumping through the hoops to get this car on the road, so Im not arguing or debating this issue.

I know how to up the boost, but how do you go about dropping the boost to 5psi on a stock motor with factory ECU? Do you swap the waste gate actuator? Where do you get one that will fit the T25 and open the wastegate at 5 psi? Or can you trick the system?

Cheers
