Had my Anni remaped over the weekend with Revo Stage 1 code. I've covered about 500 miles since and it just keeps getting better and better [:D] Gone has the tail off in power that stock mapping holds as it now just wizzes round to the red line effortlessly in any gear. Noticed a pickup in fuel economy too, but thats only noticable when pootlin' round town, which, to be honest, aint what I got her remaped for really [:D]

I've also complimented the Revo install with the newly produced, although a prototype, Forge Eliminator diaphram type valve. I actually fitted the valve a couple of days before having the car Revo'd - even then I could notice a difference on gear changing and on-off throttle response [Y]

A full reveiw of the vavle can seen here: http://www.uk-mkivs.net/forums/300520/ShowPost.aspx

I've done an install guide for the DVR (similar to DV006) and will hopefully have it posted up over the next few days.

Glad I chose a petrol over the oil burner [;)]

Well that's one good decision you made!!

On a side note, what made you go for the DVR over the 007?

Performance won't be any different but you now have the risk of ruptured diaphragms again.

Any idea what the maximum boost the diaphragms can handle?

Also, can you fit your engine cover without the vaccum pipe rubbing?

still waiting for that fuel "economy" to kick in on mine...........
I doubt it will, adaptation won't be that far off, it just fine tunes everything.

I only ever get around 24mpg town, 28-32 motorway and thats with every performance map I have had.

I've had the 006 in the past and found that it leaked boost on WOT. Seeing as the 007 is of similar design I decided it would be better going for the diaphram type valve.

I'm not pushing loony boost levels Gary so I hardly see how its going to tear the rubber diaphram.

To be honest performance is different as theres a greater seal created with a rubber diaphram as opposed to a solid piston.

There is also a tuning kit available so you can in theory adjust the valves performance according to boost levels.

The DVR valve has an adjustabel vacum inlet (it can be rotated 360 around the top of the valve) so it clears the engine cover quite nicely [Y]

I'll post some pics up later.

Diaphragm also responds quicker than a piston... hmmm I have a piston type! Doh!!!!!

Cheers guys.

I just remembered I got a little metal piston in the service kit I got from forge a while back. Must do that this weekend !

Here's some pics of the Forge DVRA:

This is the kit you receive from Forge - hose clips an' all [Y]

You can clearly see the adjustable vacum inlet, really makes positioning of the valve a lot easier!

I've chosen to position my Vacum inlet to the right, although the hose does seem a bit stretched it does clear the engine cover just fine. I may reposition the inlet at a later date. For the moment though its working fine [:D]

Good piece of kit and great service from Forge - highly recommended [Y]
