I put the oem air box with a piper cross panel filter back on today, and there is a definite improvement in performance. So the venom filter that I over tightened and broke, did cause a boost leak. It is still not quite a 100% performance yet, but certainly better.
I am not sure if I have the wrong hose clip holder or not that fits on to the bracket, but I can't really tighten up the hose clamp much or else it just bends the silicone pipe and squashes the grey bit, as shown in the picture.
Has anyone else noticed this on the Venom induction kit?
