IS THIS TRUE? my ecu is APR tuned , i dont know if that will have any effects on it... can somene please help me on this subject???? reps will be giving for any advice...

by the way i have not installed the new BOV yet...
from my experience in the past on my 03 1.8t the BOV didnt effect the MAF. I bought the car brand new and sold it @ 70k Miles . The BOV was on the car since about 5K miles with it chipped.
