@@truckingwithmadmike2984 All engines have a unique turbo whine when you let off of the throttle while running high turbo PSI. I think the 3406B with that crazy "WHOOSH" noise is the most unique, but the N14's is a pretty close second. That high-pitched screech is awesome. Cheers from New Brunswick.
