Over the past few months I have been dialing in my Simos 8.5 tune on my A8, and I have a few bases of confusion lol.

1. VCM Scanner says the bypass valve is venting boost, but shows no desired angle, and says there isn't any angle on the bypass valve blade, maybe carbon build up?

2. Excuse my newness to this topic but I understand LTFT and STFT, I've attached my log and the most I have seen is -4 on the LTFT, is there any improvements I can make on this?

Here is the best run from the 3hr long traffic riddled log
