    I have one. it does what it says it does.

    I know of another TSI Octavia owner who has one. He has the same outcome as me.

    I find that it doesn't open lower down in the RPM and I get a little flutter.

    basically, its fimer spring that can hold higher boost, but still retaining the factory solenoid. unlike some other kits that convert to a vacuum type BOV which IMO is slower to activate/react.

      Pretty sure there's a number of guys running them in their tuned Golfs/Skodas

      Pretty sure this is a good value and well designed fix for our crappy factory DVs. I will be getting one too

          They don't make any extra power, and if your car is properly tuned, then the stock DV will handle over 35psi.

          Even GFB quote there will be no advantage over stock UNLESS your stock valve is damaged or malfunctioning.

          When I talk "stock" valve, VW did a revision several years ago and changed the design to a plastic piston version which is near indestructible.

          Just keep that in mind before handing over your cash!

              I installed this in case I had the old diverter which is prone to tearing
              I found that my car actually had the newer diverter
              Absolutely no difference in percieved performance
              Even looking at the data - hard to spot the difference

                Thanks all.
                I read our vortex friends 4 pages of comments, and noted some saw perceived throttle response gains, some saw no improvement, and some recorded a poorer outcome over stock. Those with a DSG box would see least benefit due to the car doing a faster gear change than humanly possible. Those with late model MkVIs are also likely to have the better OEM valve.

                So...as a late model 2013 DSG owner, I think I'll pass on this mod.

                  The Pirelli comes with a factory diaphragm DV. I think the upgraded DV that Guy is talking about is the piston type DV, Revision D (part number: 06H145710D). Can pick one up for around $75. I replaced the DV on mine and there were no signs of tearing but nothing like having a clean piece of mind
