So I noticed today my boost was not holding past 12psi. And you hear the dv letting the boost out. It seems to do this at 90 % throttle or well pretty much if my foot is not touching the floor. I was seeing 15psi at 6k rpm but today it peaked at about 13psi. But I was able to get 15psi on a 1st 2nd run

Also when normal driving boost goes to 5psi then starts dropping into vaccum 2 to 3k rpm range.

I noticed the boost drop from 2 to 3k on normal driving once I put my boost gauge in 2 weeks ago but the boost drop at higher rpms I just noticed today. Is it normal and I just was not wot or is my dv going. If so its an excuse to get a dt dv
