I'm curious to what causing a sound I've heard both in my Sagaris and T350.

It sounds like a large amount of air is "popped" out of the in-take, it happens mostly below 60c oil (below 3000rpm as she is "cold") with medium throttle.

The engineer in me would love to know the reason behind the sound smile

Could it be a backfire from the TB's being out of tune?

I'd be removing the air box and having a look...

Yep, that's what I'd go with too, TB balance.

Thanks, will take a look smile but the local servicer will be doing the balancing!
