Yadadameans, have you boost leak tested your setup? I have the same hybrid k04 as you from HPA.

Forge got back to me today. The Wastegate Actuator for a K04 on a TSI (CBFA or CCTA) is the one I posted earlier. I asked about a DIY & the salesman explained that (as I've been reading) that it's pretty straightforward.

He said to install it with the flap closed, then preload it 3-4 threads. I also inquired about which spring to use & he siad the Yellow spring that's included if perfect for a tuned, K04 TSI (UM, APR, etc.) at 20-24lbs.

I've ordered one & will post a DIY once I get it.

I also have a Forge wastegate actuator that I'm putting on my OEM Borg Warner K04-64 that I'm modifying to fit. Thanks for posting about the recommended pre-load from Forge. I'm also going to ask Stratified how much preload they want me to put on it since they have tuned with the actuator before.

I suggest you guys changing out the DV on the HPA to the Oem Rev D one. The one on the HPA isn't as great and it's like a knock off even though it's still a piston design.

I'm running the actuator they supplied with gfb dv+, works well

The actuator it comes with is actually really weak, but if yours works fine then that's good. I replaced mine with a kinugawa actuator and you can feel how much stiffer it is than the one HPA provided

I actually meant the diverter valve solenoid/actuator ....running their stock wastegate as well don't seem to have any issues at all....just a boost leak with their shitty machined parts

I run a Turbosmart plumb back on mine with no complaints. I agree the one they supply you with is a cheap knockoff

This is correct. 3 HPA turbos DV already failed only 2 months. I managed group buy for my customers. And 3 of them already stuck and throw error code on DV.

Replace it using D, and working well now.
