as the title says im getting a really bad whining sound from the turbo area once i hit 10 psi. I had a custom realtime tune on the car and i took the battery out to do the sparkplugs. once the car was drivable again, i forgot to upload the custom tune and i was just driving around on what i believe is the stock tune. so i uploaded the custom tune to the realtime section of the AP, and im constantly exceeding my target boost. i shouldnt even be hitting boost in first gear but i keep hitting 5 psi, and in second i shouldnt be passing 5 psi, but i keep hitting 15 psi. and this sound literally just started today about an hour ago. does the ecu need a time to re-assess itself after uploading a tune? What could this super whining sound be? why does the car keep exceeding my target boost pressure for the gear?
