After chasing a ghost for some time now, changing half the sensors I already changed along with a brand new harness for the engine I think I found out my problem with system running lean and misfire...my injectors were supposed to be 750cc but it seems like they were 550cc when I did a flow check on them. Installed brand new 840cc Siemes DEKA 5 which all flows 925/930cc at 4 bar.
Just pressure tested my system and everything is perfect!
Also got my carriers so that R8 ceramic brakes are plug and play.
