i have the same excuse as everyone else- i tried searching but found nothing on this.
i switched out my dv after i got chipped with apr 91 with a evoms dv and installed it reverse. now every time it lets off boost pressure, it has the same blowoff noise as the stock one but followed by a high pitched whistle. Is that normal? If someone else with the same dv has the same noise- great. The sound doesnt bother me but im a worrier. Any feed back would be appreciated. Thanks

 

i dont want to be a thread stealer but, i have a question about the stock DV.... mine makes like a flutter noise under boost, when shifting... is that suppossed 2 happen? b/c i just started noticing it now... and i have had the car for almost 2 years... its a 2000 1.8tqm

 

have you ever tried to suck and blow at the same time, that's what happens when its the wrong way round

 

you put it on backwards and you're wondering why its whistling?

I've heard of ppl putting there's on backwards but I think audi put it on the right way for a reason...

try reversing it.

 

luckycharms are you chipped w/ original DV? 710N? your DV might have a tear/crack in it. get a 710N.

 

ya put ur dv back in the right way. i've seen people put them in both ways and done tests to see any performance differences. Conclusion: insignificant at most. And luckycharms if your just noticing the problem now then your dv probly finally gave out and its time to get a new one(especially if your car is chipped).

 

im not chipped as of yet, but it is in the plans... you all think i should get a 710N or the forge 007.... i want sometihng that is going to make the sound a bit louder but function properly...

 

do yourself a favor and get the forge especially if ur gona get chipped its the last time you'll have to worry bout ur dv and will be safe to run almost any boost ur gona get out of the stock turbo

 

yep my forge is tha **** nver have to replace just clean it and re grease once a yr and its good to go again.... as for the 710n no cleaning there just throw it away and buy another one... when chipped they tend to go out after a while anyways do once and do it right go forge or balieys of evoms not stock tt valve

 

yea forge is the shizit man i loved mine....... and it doesnt matter if you install them forwards or reverse it should work just as good either way
