DIY Clutch Delay Valve (CDV) Removal

[pk8]

I went for a long drive today and I can 100% say that the rev matching is complicit in my 1-2 shift problem. With rev matching off for the majority of the drive, I had zero dodgy shifts. As soon as I turned rev matching back on, the hesitation and poor shifts returned at random as per usual. My CDV has been deleted but my gut feeling is that it has no real bearing on the issue, at least in my car.

My issues have resolved since the CDV delete and 100% happy with my shifting right now. I don’t know what to say…

Yeah, I don't know. We're probably talking about two different issues which present similarly. I don't know either.

Big bonus of this mod; shocking the drivetrain with a clutch kick is so much easier now.
