Bad BCS or MAF

[eclipse1987]

I have a pretty much stock eclipse gst auto. Heres my problem, when i run completely stock at 5,000 rpms my car studders and wont accelerate any more only when I'm driving tho. When I'm parked and rev up fine. OK but when I put my MBC on, the studder goes away but then my MAF makes a fluttering noise as if the air was coming back out of it and my greedy BOV doesn't hardly work. The fluttering noise in my intake is louder than my bov. any help would be great thanks guys!

You're getting compressor surge with the MBC on there.

ya see what you do is take a .22 handgun and aim for the BOV..
