ok so i bought the zzp bov and welded the flange on my dejon charge pipe i have the dejon lower pipe too but no relocate so i was driving home from ky yesterday and did many pulls on my hhr ss and when i got 5-10 miles from my house i got no boost so i stopped the car and popped the hood and checked for a boost leak (by the way i put the pipes on that day and had gotten tuned same day) soo no leak and started the car back up and i got boost back then maybe a mile from my house my check engine light came on and it was code p0101 mass air performance again no boost leak so i went further and found when i give it gas the bov opens twice once after i let off the gas and the other in vaccum i was wondering if that was normal
