DV Valve question

[wychoi36]

hi, i have 04 1.8T stock right now and trying to go for a large injector program. Either APR or GIAC.
When I searched, I read many threads saying that I may want to get a new DV Valve as well.

which one is the reliable one that I can use?

thank you,

Get an OEM 710N DV (from the Audi TT) or anyone of the aftermarket DVs (Hyperboost, Forge, Apr). They're all the same.

Some people will say for you to search more but since I'm in a good mood I'll help you out. You basically have many options when it comes to the metal -piston type DV. Forge 007 is a very popular choice as you can put different springs in the dv to match how much boost you are making. However it is over $100. If you want a good cheap option there are the 710n dv that are available at the dealer and places like ECS that are much better than our stock dv. Also released last year by APR is the R1 which used a cool idea but has received many mixed reviews from users. When it comes down to it, it really is all dependent on what you want to pay and what is readily available to you. FWIW I run the 007.

thankx for the quick replies guys!

if your considering sound, run a EvoMS DV. I ran this DV reversed on my GTI (with intake) and it has a nice blow off high pitch to it =D

I run the 710N, on my K04 setup.

Im thinking of getting a forge 007, ive seen it priced from 135-150, are there any other DV that are cheaper than forge but reliable?

[oregonaudi]

a little off-topic suggestion would be to look into pinging problems with giac software and the innability to tweak the settings at all.
It has been a pain in the ass for me.
As for price on the forge, those you listed are average, but you can pick a used one up for like 70 in the classifieds

Could you be more specific with the piping problems and tewaking the settings?

EvoMS DV. Is that any better than APR's DV Valve?

Yes, the Audi 225 TT OEM DV last 3 numbers in the part number are "710N"

Very reliable, very inexpensive!

giac puts a firewall on their newest software that makes it impossible to tweak the file via lemmiwinks. Not only does this limit your ability to alter your file for personal preferences, but it also prevents an east fix to the aggressive timing on the giac big inj file. This means that once you go giac and you experience engine pinging (a common problem, I would post a link but my phone does not copy/paste), you are essentially stuck with it unless you swap plugs or something to compensate for the mild detonation. In my case, plugs didn't work and I am currently running a file that is conservative.... and I just consider myself lucky to have a good tuner that cared enough to help me out and stop the pinging
sorry for the ramble

They're all the same. Seriously.

[diztek]

when my dv goes bad, im getting the 710. its sooo much cheaper.

right now i have the evoMS billet dv and its been great for 50k miles.

Here's an Audi TT 710N valve on ebay right now....

They're all the same. Seriously.

they aren't even close to all the same.... Forge uses a metal piston style for there DV's and APR uses a diaphragm style (which seem to tear) i am running the new Forge splitter DV, its a hybrid 007 that recirculates air and blows off to the atmosphere at the same time... i like it, although its loud as hell when it blows off... but no rich condition or check engine light because it retains the recirculation characteristics as well

i think he means that with a tiny K03 they are all the same... i really dont think a K03 can push the APR to tearing point. I used to run an EvoMs and now a forge 004. as far as i can tell, there is no difference in performance at all... i do get a little surging with the Bov when i prolong the blow off(slowly letting off gas). i believe the ECU is fast enough to compensate for being too rich for a fraction of a second

I never hit full boost with 710N w/ 1+. Forge is much better.

One problem with the 710n is the small vacuum connection, it is identical to the old DV which means it is recessed and almost impossible to get a clamp on, unless you reuse the old compression clamp that you salvaged off your old DV or get a new one from Audi. I would have preferred to know this and would have spent the extra for a better setup.

I ran the Hyperboost DX DV for 2 years. Now been running the APR R1 since July 2007. Both were used with my setup (car hits 22-23 psi during summers).

Both feel the same to me.

Originally, I was going for GIAC because it is the closest one. However, if the newest software is that much pain, I would rather go for APR. I just don't like to deal with minor problems after spending money on upgrade.

The OEM 710N is a great all around valve. I got rid of my Forge & uninstalled my hyperboost because the car was smoother with the 710N. If you want a hyperboost let me know. I one for sale cheap. I prefer the OEm 710n w/ my K04.
