Ready to race!
I installed a turbo discharge pipe tonight and noticed a "flutter" afterwards that I've never heard before. I've been able to nail it down to around 3800-4000 RPM in either 3rd or 4th gear when @ WOT.

Current related modifications are an Evoms intake, DV+, and this new pipe. This is at stock power levels still.
Here's the graphed log from a 3-4-5 gear change on the highway. What do you guys think of that second boost request hump on each gear change?
What I'm trying to determine is if I have either a simple boost leak from not tightening a hose clamp enough (causing air to leak when it builds up high enough and then the seal re-seals once enough has leaked out) or if I'm actually getting some compressor surge. The latter is known to occur once tuned but obviously I am not yet.
And of course, the big question is, "is this dangerous?". Thoughts?
