I don't care what the GFB DV+ says. There was something bugging me but I couldn't put my finger on it as boost was slightly better than on the OEM DV, so it works. However Steve Jr suggested trying the manual Evoms DV and I gained another 2.5psi for the same duty cycle. The car felt stronger again over the GFB and sounded a gazillion times better ( too much sound for pussies!
)
On a slight down side the GFB is better on part throttle, but that's about it really.
I can only surmise it must be leaking under load, but the advertising bumf says it should take anything you throw at it!!
If this is designed for a K03 and they are bringing out a K04 one then I was mis-sold as it said on their website that it was good for the Golf R!
