It Seems that the power & torque needles jump around ramdomly for no reason just idling, also when testing needle for boost pressure is completely missing. 
Can you please post the engine file that this is happening for?
After playing the game for about an hour all of my engines started to do that. It didn’t matter if it was NA or TC, an I4, I6, or V8. the needles on the power gauge just started spinning in circles. Also the UI that displays the stress on different engine parts also quit working at the same time, not sure if the 2 problems are related or I just experienced 2 bugs randomly.
I have deleted the file already… sorry

Yes, Power gauge Problem the same but, no problem with
stressed component display yet.
Anyone else notice the wastegate sound on starting an engine?
Me too
