I put my ZFR on over the weekend, It has a Trifecta tune file and a Forge atmospheric BPV valve. I used the search bar and found quite a few people complaining about this but didnt see anywhere anyone solved it. I'm unsure if its a tune issue, a BPV issue or the wastegate on my turbo. I get a VERY loud flutter sound when I let off gas after giving moderate throttle. Anyone ever find a soulution? I'm not wanting to accept that its "just how they sound".

 

Video to show problem?

Edit: took out second part because completely wrong.

 

It's just how they sound.

 

I had turbo flutter and turns out my vacuum tank under my intake mani was cracked. May not be your issue but may be worth a look

 

I got turbo flutter on my dune buggy and it sounds freaking awesome lol

 

Check your pms and text me.

 

I dont have any videos of my own yet, but I found some dead on examples. This is what I would like to hear no flutter sound at all.

This car is just like mine in sound
Kyle, I'll have my intake off next week to try to clean valves and swap back my TTR intake for stock. Wert, on it, I'll send you a message tomorrow. Thanks guys!

 

Top vid sounded like he wasn't lifting between shifts, which means you won't hear much noise from the turbo at all. Not sure if that's the best example to use, but honestly the bottom video doesn't sound bad either.

 

Honestly mine sounds like that too when i get into boost and let off the gas, but when I do quick shifts and only does a screech real quick as the first video. I don't think it is horrible, but actually pretty nasty.

 

Same problem still! Sub'd

 

bump

not yet solved? thats just the way it is?

 

The top vid is me, I was shifting between shifts. Just shifting very fast lol, it doesn't flutter cause it was such fast shifting. If I just let off like a normal shift it sounds like the so called "flutter" we have all experienced. I think that's the way the turbo is...

Yep, same here. If you go on my youtube account and watch my EFR logging video, I was pretty much in 3rd just going on and off with the gas. You can hear the "flutter" in that video clearly. I believe it's normal.
