how low in RPMs are u talking about? if its too low i think u jus needa downshift. the sound i hear is like.... i mean i can tell its the turbo cuz its pretty loud. but i dont get any pulsation thru the driveline...

mine certainly feels that way, not sure if its actually thorugh the driveline, or just vibration from the flutter itself... my flutter is pretty bad

I didn't elaborate very much.
I usually feel it when I'm at about 2100-2400 rpms in 4th, and the turbo is just beginning to spool up climbing a hill. The engine isn't laboring, I know that. I also feel it in 5th on the highway, or going up a hill, accelerating from cruising speed with light throttle application. It's just a small pulsation, power doesn't seem to be affected that much.

seems like there are a lot of different degrees of it. i get it in every gear and RPM with anything above 0psi its a loud clicking noise and pulsation, boost bounces between 9.5 and 10psi. i assume because i have a crappy bellmouth downpipe that boost creeps alot and its the boost control trying to counteract it.
