thx for your help.

"The fuel damper reduces fuel pressure pulsation between the fuel injectors and fuel filter. "
so...what if I take it off and replace it with a straight thru adapter?

Very very good point.
I wonder....especially with a FMU ramping up fuel pressure.

Actually, now that I think about it, it's proportional to boost.
So, the FMU disc ratio, ie 8:1, 10:1, 12:1, etc, and type of boost, ie exponential or linear, would determine it. However, if the stock system only ramps from 34psi to 43psi at WOT and it requires a fuel-dampener?
Boost is going from 43psi to 80psi, even 100+psi in maxi-overdose's case.

Is it really necessary to remove it though?

just undergoing some process of elimination of the possible causes of my lean problem. if I can get a high pressure but still running lean....something must be wrong inside the fuel rail.
btw, someone's selling 2k1 injectors for 70 bucks apiece...what do you think?
UMD - my car's running leaner than usual from mid range rpm and the fuel pressure was low at that point...and without losing too much power btw. seems like it doesnt receive enough fuel from midrange rpm when boost just kicks-in.
just FYI

He told me $600 shipped for the injectors/rail/FPR/damper, so he's probably trying a bid war.
I only wanted one though.
