Well I tried once more installing the pro-flow by twisiting the filter as Damien said, also there is absoutely no obstruction between the filter and pro-flow, I still have the same problems of my car "hicupping", feels like little short bursts of fuel cut.
Anyways I will be sending it back for a full refund.

by the way everytime I reinstall my stock MAF my car runs great again. I'm just not one to keep dealing with headaches, SVTCUERVO thanks for this group buy, serously, great job.
People need to know the Pro-flow calibrates these not svtcuervo.
