Like Jacko I am only getting **** weak boost since installing my Hyperflow FMIC.
Checked all the hoses and clips.
Maybe the BOV?

 

OK panic over - Hose came adrift at the inlet manifold.
Well first impressions .
Fcking hell !
I think the VF22 can breathe now.
This machine is seriously quick now.
Very impressed by Hyperflows quality , support and directions.
Thanks Kevin.

 

Had the same problem on my fmic - a visit to Halfords to sort out a new jubilee clip

Does this jobbies bloock the raddiator like on the aps one? - or did they put some thought into it?
