check battery first
make sure your battery is good. Autozone will battery check for free.
After that, make sure all your vacuum lines are ok, esp. the one going to the combi valve.
Next we need Vag Com measuring blocks 32 and 2. post results.

These can be related to your dv relocation issues >>>
If something is leaking or incorrectly connected.
They are all sporadic so they may not have all happened during the same ignition cycle and didn't happen on the last ignition cycle.

Actually after I did mine (when I did my FMIC) >>>
I occasionally got the MAF high input and high charge pressure codes but they never caused a cel or anything noticable. This is when I added the **** and the codes never came back.

Cooler air= more efficient boost= higher PSI (until it stabilizes)...>
Normal to see a bit higher boost after a mod like that for the above reason...Usually it will drop a bit lower than it was due to the pressure drop inherrent with the bigger Charge cooling capacity. A Boost Machine will tweek that back easily..

This was a year ago, it's fine now >>>
I gave it a couple of weeks before doing anything, I figured the **** was a nice addition at that point anyway. I still had to do a little tweaking to get my fuel trims back in line because it was running a tad lean.
I also run an n75h valve so some of this didn't surprise me.
