GFB DV+ OEM Diverter upgrade kit
Bigjimknickers:
Cheers Dan, I'll be sure to buy one before my visit, I'll be getting it done soon, had my VW caddy mapped last year & is been a huge improvement.

Finally installed a VWR intake to compliment stage 2. So far everything is great EXCEPT that ridiculous whine you get on boost.
I've done a bit of research and many have said that the DV+ removes the whine? Some have also said the Rev D or G also gets rid of the whine.
Can anyone confirm any of the above?

I have a VWR intake and a DV+. What whine are your referring to? The sound of the DV releasing pressure when you take your foot off the gas pedal?
Dan_FR:
The whine is a K03 thing....... It's a harmonic resonance caused by the intake - some cars do it, some don't. The DV+ will not make any difference, neither will changing to a Rev D or G. Don't forget the valve is fully closed on WOT when the whine is present.......
Adjusting the intake can help though. The first intake I made for my car whined terribly - horrid noise. I ended up chopping and changing pipe angles & lengths until I completely eradicated it

Thanks for the explanation @Dan_FR! :drinking:
