Link to Hoppen's UrS MTM-based upgrades
Note that Hoppen now calls Stage 1 with the 3.0Bar MAP sensor what we have been calling Stage 1+. Also note that MTM Stage 2 is RS2 goodies but NO injectors. MTM Stage 3 is with RS2 injectors. Not a real aggressive tune in either case.<ul><li><a href="http://www.hoppenmotorsport.com/Audi.S4.S6.Tuning.htm">http://www.hoppenmotorsport.com/Audi.S4.S6.Tuning.htm</a</li></ul>

That thread was from 2008. I haven't seen shavedquattro here for years so you are unlikely to get an answer from him. However, based on your thread, I put a call out for Lehmann Stage 3 photos on another Audi forum and I got one good response. Looks very similar, if not identical to yours (except for the "3 Bar" and "Hopp" notations):
