Actually I never had the problem until the weekend. I found out why on Monday when doing some logging.
I had flashed a new tune for the weekend with map switching and didn’t have time to test it. Turns out the boost was going above requested so the throttle plate was being closed to 50%.
A quick log over the weekend would have shown it.
The pressure differential front one side of the plate to the other was causing it to pop off every now and then.
So a tweak to the tune and the problem is solved.
That’s not to say I don’t have some plans to stop it from happening though.
