73k miles. Happens at its own speed and isn't synced with the rpms. It's either there or not. Only audible in residential and in parking lots. Once above 3k it's gone.

The car always made this noise. Years back when you brought it to me for stage1, then stage2, and still now.
-Tune is solid. Very conservative. Zero recorded knock, no matter what load is applied. Numerous logs, numerous checkups, etc all show perfect health. AFR is dialed in perfectly. Boost is low (for the setup).
-The engine is in good health, just did compression test a few weeks ago, less then 3% variation between cylinders. Plugs looked perfect. No leaks, and everything nice and clean.
-All new exhaust gaskets: header, up, dp, exhaust, etc.
-All maint done on time.
This car ticks just like every other subaru, just a TINY bit louder at EXACTLY that RPM range. Before that its fine, and after that its fine. Idle is fine.
So yeah........Figure that one out
PS: we never opened it up (for obvious reasons) but valve/lifter tick is probably a fair guess

I'm totally confident the engines health is perfectly fine, thanks to vladi being an awesome
Tuner. I'm just curious as to what it is. It's one of those things other people most likely wouldn't notice, but something that drives me nuts!!!

Think I just need to go to town on the dynomat and some insulation.
