    Does anyone know the stock boost pressure for the 3.0TDi (CAPA)? I am trying to figure out if my car has been mapped. I have done some logs and have seen readings as follows (24psi peaks). Many thanks!

    You are better off logging the fuel injection amount as this is what is really modified in a remap. The actual amount of boost may not be much more than stock as there is plenty of spare air as standard.
    Stock map injects around 64mg/str fuel between 3-4K a remapped car more like 75-80mg/str and there will be a lot more fuel injected at lower RPM. Standard 2k rpm max acceleration 35ish on a mapped car more like 65 ish.
    On my CAPA injected fuel is block 102.

    Looks like it is probably mapped looking at this log (red is RPM/100, blue is mg/stk)
