Running without a DV- benefits other than noise..?

I've been converted to running no DV. I was actually advised to by several highly regarded experts when going to the FMIC, but people considering it should be aware of one downside on maf based ECUs: it can make the car judder a bit when doing on and off throttle transitions. AFAIK this is because the maf registers air coming back the "wrong way over the sensor" and just erroneously adds fuel.
My squirrel blender sound is rather on the loud side as I have a FMIC and K&N cone filter; certainly gets the attention of people in the car
For what it's worth, the advice I've always been given (again, by tuners and mappers) is VF30 onwards fine with no DV, earlier than that and you're risking it! Take it or leave it

Hmm I've got an adjustable GFB vta DV and when fully closed the car has plenty of chatter but fully open the car seems to run a lot quicker and only has that pleasing tiiishhh sound that older turbo drivers now seem to hate!!! I've never had an issue with my vta. Stalling etc etc. Far as I know Rally cars would still use them if not for noise restrictions.
Mitsi TD's are allegedly really robust units and most people on here say that it perfectly fine to go DV'less on them.
To back this up, my 1993 WRX has the TD05H (the original one AFAIK) and it's perfectly fine - absolutely no noise/smoke, and pulls like a veritable train.

Found my bung, and tried this over the weekend, car seemed more jerky on the M62 when lifting off at speed. On balance I prefer the car with the DV connected.

has anybody tried this on 1999 uk turbo? as i would like to do this to my car but before i get the blanking plate made i thought it would be a good idea to see if any body else had any problems. thanks in advance guys.
Guys, had an idea... If the standard valve is fine (and I think it is tbh) but running without one has benefits when driving enthusiastically, would it make sense to somehow convert it so that it is switchable between the two? I'm thinking some kind of solenoid valve between the dv and the intake pipework, that effectively blanks off the dv when 'active'? Any thoughts?
You car has the 'strong' Mitsi TD turbo (TD04L), so it should be able to handle being run DV'less, yes.

Given that the TD04 is already very responsive, there's minimal performance benefit, that the resulting noise on a standard car will be very quiet anyway, and the possibility of engine damage secondary to MAF sensor degredation, it's worth you considering carefully whether it's worth bothering.
I blocked off my DV yesterday after fitting my FMIC and reading this thread, i was expecting a really good noise when changing gear when on full boost, like in the video at start of thread.
Sadly i got the "gush" noise as described on page 6 any ideas why i was getting that?
Is it because i have a kn open cone filter on the car? do i need a proper induction kit for the noise?
