really bad dv chatter

[pd9264]

iv just fitted my k04 turbo to my gti ready to go stage 3. i havent fitted injectors yet. but i i just run the engine for a bit and i now have really bad dv chatter. im running a itg filter. is this normalor have i done something wrong along the line.
  also if its normal will it be like that at stage 3 as its too loud and doesnt sound right. many thanks

ITG panel filter or ITG Maxogen intake "Filter on a stick"??

[pd9264]

itg max. iv also tried it with the standard airbox. extreme dv chatter with both. iv tried a revision g and my forge one still the same. once i get it mapped will it stop. because i dnt want to go get it mapped and something is wrong that iv done.
   i would of thought something is working properly to give all the chatter.

The standard airbox shouldnt really chatter to be honest. The ITG maxogen is one of the loudest intakes along with the EVOMS. I cant see the noise stopping once mapped.

right iv had a further look and found that my dv is  not working at all. iv tried 3 different sorts of dv on it now. a c, g version and a forge one. so it cant be the dv. it must be whatever controls the dv. how can i test the supply. it worked before i fitted the k04. so its gota be something on the k04. could i swap it over from my k03.

Sounds like its not wired up correctly.

its only a plug connector. all iv done is pulled the cable from back to front and plugged in. what controls the dv to open and close. is the n75 got anything to do with it.
  maybe the k04 turbo i got has a faulty n75 valve or something.
