ok! Thank you! found it. Cleaned the connection and clamped it tight. Still cuts off on sustained boost.
Yes, I have a round red fuel pump style relay instead of the rectangular yellow one.
I guess Ill try replacing the overboost unit and see. I have a spare new red relay so I could check that too. The car shuts down when I disconnect the white wire to the overboost switch so its working under normal situations.
The stock waste gate has a new heavy duty diaphragm and 1 bar spring installed not more than 600 miles ago so I doubt it just failed.
Perhaps the overboost switch is bad or too much exhaust flow plus 1 bar spring= overboost reached before the spring opens the waste gate..?
