Hurdy:
The Forge one is a piston type affair and is faster acting and more efficient than the diaphram type. They also claim it hold on to the boost longer, but I doubt there is much in it.

It is a good solid performer and a preventative measure against diaphram wear/tear.

You also must remember that the Forge item needs lubricating every so often - it isn't a "fit and forget" part :nerd:

Janner_Sy:

i was under the impression they moved the DV to the front due to heat issues from the turbo. especially when running more boost. So if it is the same as the tfsi DV it will still have the weak diaphragm

john_o:
the location was changed by VW, however the problem can effect cars with relocated valve (inc ED30) esp when remapped
(just relocation to avoid heat, does not seem to have resolved all its problems)

My personal opinion is to keep the OE until it fails, then consider a swap to Forge DV or a new OE part.
For me this is the biggest reason to log boost or fit a guage when the cars running well, so you can get a feel for normal boost over the rpm range(and conditions) which you can compare to when a problem rears its ugly head.



CocoPops:
As per the post above.

My car does feel like the peak boost is at 4k plus.

I really wanna get it dyno'd again to see whats what. Time is an issue at the moment tho :(

john_o:
check out SteveP thread here  http://www.mk5golfgti.co.uk/forum/index.php?topic=993.0
Its his original SC map against the new version.
I can see from the original torque curve it starts to rise again at 4k+ so that makes sense and corresponds to your comments.
I would expect the car to feel very different with the new map, and have an earlier peak rpm 'feel'

StevePG , how does your new SC map feel compared to the old? in terms of rpm peak feel?
