Default Running DV less setup advantages?

Can anyone explain what the advantages of running a DV less setup are, I have a SC46 billet and fitting a FMIC in the next week and was wondering if its worth it or shall i keep my chav horn?

Cheers

Retains boost pressure if your slick through the gears like me Some reckon stalling the turbo makes daily driving more laggy but categorically I can say this has not been the case on both my scoobs running DV'less. I much prefer the response on gear change. Ditch the chav valve anyway and go recirc if anything. Worth noting that my TD05 doesn't see more than 1.4 bar, greater boost pressure may be of greater detriment to a much more valuable turbo such as yours

Running 1.6 bar at present, Was told the 46Billet was good for the extra pressure put on it by running DV less

Did you have it mapped in? Most people that report issues havent' had map compensations for the change in air/fueling...

I will also be trying this out on mine as
1. I hate the chav valve, its way way too loud even screwed all the way in
2. im sure its sticking open at times! So if its not there it cant stick
3. Much prefer the noise it makes DV less imo anyway

And if i dont or cant get along with it i shall be going back to the standard re circ valve, although im sure i have read somewhere on here they give up the ghost towards the 450 marker? Any ideas??

I think its a bit of a sign that alot of people that say certain turbos can handle running DV less also see a turbo as a consumable.

The fact is that even if a turbo is sold as being able to handle no pressure releif, it does massively increase the loads on its bearings and will therefore inevitably shorten its life span!

Pressure releif valves are good! VTA valves are bad (if youve got a maf)! ..... so that suggests the only way to go really is a recirc! And its widely said that the standard recircs are as good as any.

I fancied trying DVless but was told it may kill my turbo, has anyone had turbo problems with this?
