Engine sound glitch with engine swap

I decided to use the new Fiat Dino to do some career events. I have effectively a muscle tune for straight tracks with an LS7 motor swap and the stock engine with more handling upgrades for tighter circuits.

So I loaded into a tight circuit went to the tuning menu swapped out the Chevy engine for the original…

This happened:

That appears to be a stock LS7 revving to 9k…obviously the sound file hasn’t switched to the correct engine although the rest of the characteristics of the car were correct.

Can now confirm this happens both ways, basically if you load a swapped tune from pre race you will have the sound file of whatever engine you had when you loaded the event. Only way to get the correct sound is to leave the event and reload.
