Yep I have this slight hesitation below 2000 rpm, it is better since n249 bypass, any way can someone throw up some pics of where and how the standard dv fits, went to replace the e.bay thing that's on it, but now I have a standard one, I can see the one on it is totally different, it sits free floating in the air just behind and above rear of engine, it has a silicone hose coming out of the left standard DV size going to a metal pipe to left rear of engine, then a smaller pipe, going to somewhere behind PCV valve ( N75 Valve ), then a smaller hose again ( 4mm ) going from a spill on the top of DV which bypasses N249, their is what looks like a place for a hose, just after the airbox, on the outlet pipe from airbox, which has a bung in it, I assume this is where the standard DV or forge 007 etc goes to.
Help !!!!!!
