I was driving a Nissan 370z and noticed a crackle or stutter in the audio, so I unpluged my home theatre system and played through TV speakers, same noise… Looks like this was also a problem in Forza 5 any one else experiencing this issue?
is it maybe the exaust? some cars in real life have something like you are describing if when letting off the gas when red lined. it sounds like a quick series of mini backfires when the rpm are dropping fast?
