Interesting. My initial thoughts were also turbo surge, but my understanding was that didnt occur until higher boost levels. Surge is an issue even at 10-12 on the boost? (IIRC, was mid to low-2000's in the RPM range in 80T, upper 2000's to 3000+ in 80E).
Chris: Feathering the go-pedal is my interim fix. Would like to eventually not have to worry about it.
Hook it, I'll pull it.

Yep, 6637 installed.

So if I *dont* get the woosh, it's likely surge that's making the other noise, and I need the WW.
If I *do* get the woosh, then what? I think this is where I am...

What time frame are you looking at, and definitely let me know if that helps!
I do recall this happening, not sure if it's specifically post-shift (I think yes) or coming off the pedal (dont recall this one...). Will check it out next drive and report.

If you get the chicken chirp with higher RPM's then it is turbo surge. And the WW will help.
