I cant go back to a DV unless I change the ECU now, according to the previous owner who worked for an Audi shop, the ECU was dyno tuned by the Audi spec shop to run a k04s @24psi with a Tial BOV and he thinks I will make it worse with a DV on that programming now. My car was to be a clone of the shop owners car which had already reliably done 26,XXX miles on this setup at the time. I explain it better here https://www.audiforums.com/m_435559/tm.htm
