i'd take the battery off for a few hours, just to give it a "reset"

boost leak check pipes and do hand brake turns that will fix it right up.

Well got back in the car to drive home and back to 25..................... so no idea what the go was. Maybe the car just dosnt like the wet weather.

5psi sounds like the spring on the wastegate (i've dynoed my car with n75 unplugged and that's what it boosted IIRC), so perhaps your n75 was sticking or not getting a signal...?

That sounds on the money, as the car was running fine unlike when it has a boost leak and i did check n wiggle all the vacuum hoses once i stopped so maybe that fixed it ?

No hand brake turns but did test run on my driveway and can report boost,clutch and peloquin all worked fine
