Ready to race!
I was reading this thread as I recently installed the Unitronic intake and get the whistle sound roughly between 3-5k rpms when I am on the throttle.
CTS does make a complete DV replacement for those not wanting the BOV version.
Just curious if anyone has installed this after getting a whistle noise under WOT with a new intake and if it resolved.
I love it! If he was closer I would let him borrow mine. The idea here is to test the data back to back for OEM "D", GFB DV+ with spring, GFB DV+ without spring, CTS BOV, etc.
That's so weird that you're running into a lean condition whilst I'm running into a rich condition. I'm at -9.4% partial. But that's always been the case with this CTS Intake. What I can also vouch for is that this DV has NO impact on fuel trims, throttle response or over-all drive-ability. I regularly scan my car with VCDS and can also report no errors relating to it. I also believe the car is pulling a little bit harder and I can feel a difference between it and the Rev D DV. This is definitely a nice upgrade, albeit a little expensive IMHO.
Sorry mate, that's not compressor surge. It's the wastegate controlling boost levels. Nothing wrong with that and all modified MK6's do that. It annoys the crap out of me that every one immediately thinks "oh noes - compressor balls!" when you have a car with a wastegate AND DV. Anyone claiming that the "rattlesnake" noise is surge is indirectly implying that neither the wastegate nor DV on our cars work. And that's just plain wrong.Is it a whistle sound, a hiss, or a rattlesnake? Hiss would be normal turbo spooling up, whistle may be leaking DV (but that seems surprisingly rare for modded Rs), rattlesnake is compressor surge flutter (https://youtu.be/VDafiOvKfXs).
If you have a whistle from leaking DV, one solution would be the Go Fast Bits DV+.
Just put on a CTS turbo BOV on my 2015 GTI. When I am at half throttle with a little bit of boost and shift to the next gear (usually 2nd to 3rd), the BOV stays open for 1 second then closes like its taking a gulp of air.
This only happens every once in a while.
Has anyone else witnessed this before? I did a search on the net but looks like I couldnt find anything.
Have plenty of our customers running this with positive feedback. The CTS DV would be more popular on the MK6 and BOV on the MK7 since the MK6 still has MAFAny updates on this? Interested in this BOV
