4.7 diode is still going to allow the ECU to get the full signal from the boost sensor since your only running 14psi. The 4.7 should be used when running over 18psi. You need one that limits the signal down very close to what your ECU is requesting, if you are 300mbar over the ecu can cause issues.

You might want to log block 115 and 031 if you have a vagcom.

 

My n75 is still plugged in by I just looped some vacuum line on it. I run a MBC. Since I've been having problems with my car, I keep at right around 11psi but I do have the 4.3v1w diode mod. As far as I understand it, I am unable to go into limp mode because I run only the MBC, correct? Just tyring to verify so incase any else has this question. My reason behind my theory is that the n75 controls boost by means of the ECU. If I delete this, then there's no way for me to go into limp.

 

Correct. But the ecu can still close the throttle and open the BPV if it wants. Doing that will decrease boost and power.

 

Even after I did the egr/n249/sai all that stuff deletes?

 

ECU can still close the throttle body if it can still see that the boost is higher then requested. So you need to make sure the diode being used caps the boost readings right at your max requested boost.

My ECU kept closing the throttle because my 3.5" maf was being maxed out, that is when I decided to go stand alone.
