This may sound wired and I think it might be the wastegate opening. But on low throttle usually in the subdivision, when it holds in a gear and doesnt shift out I hear a weird noise coming from the engine. It lasts a second or so, and to me I think its the wastegate opening. It also seems to loose a little power when this happens.
Is this normal for it to open this early on and if so how can I get it to hang in there longer.
