Happens in all gears. I am not sure what RPM, but it happens right around 12-15 psi.
I guess I will try the next spring.
TiAL Sport,
Can I contact you to get a new spring or exchange a spring? Let me know.

It is under acceleration, when I boost. Usually this only happens when I am trying to speed up to the normal speed limit of SoCal - 80 or when I try to pass people driving slow.
The only thing I have left to try is a new spring. Hopefully, I wont have to shell out $35 bucks for a spring.

Interesting...my Synapse doesn't do what's in that video at all. The Synapse seems to have trouble when I am trying to maintain a constant speed. So if I boost to 80mph in 5th and I back off the throttle to about 20% throttle position, that's when my bov starts fluttering.

It may be like that video but it won't do that if I go WOT. It only happens partial throttle around 12 or so PSI. The BOV is awesome at WOT, holds boost and everything. But when I try to pass someone (normal passing) it will start to boost, then flutter somewhat like the video. If I stay on the gas the same way, it will buck back at me and blow off. If I let off the gas, it will blow off and I can get back on the gas.
I will take a video tonight, it may not be the best but I will try.

I actually had the exact same problem on my GTi with the stnd TiAl 50mm... though it happened at 2-4psi 30-40% throttle mostly in 5th gear. Turbo was a t3/t4 50trim... that eventually blew and I got a 57trim with larger exh housing....problem went away.
My issue 100% was turbo surge

Cry...or get a larger T-body that may work.

I have made sure EVERY clamp is on tight. I don't have the tools to do a boost leak, I should but that is besides the point. The ONLY thing I have changed from when I got tuned (boost leak test done then) is the BOV.
Here are the videos I took. Second one I go through 1st and 2nd, then 3rd. I am on streets so I didn't want to be too loud to attract any attention.

Like I said in a previous post, when I downshift before the turn, partial throttle through the turn... problem occurs.
It happens in ALL gears. I don't think downshifting is a good solution. If other people aren't having this issue, there has to be a different solution.

I am experiencing the same thing with the surging of the stock 8 turbo. I am planning on going ETS T3 with prob 6262. Should the surging stop then? Anything that can help mitigate the surging besides the downshifting with the stock turbo?
