Ok... Updates!!

Boost flutter problem.... (at low throttle)

I have aftermarket uppipe
I have new o2 sensor
I have new coils
New spark plugs
New MAF sensor

Overall car feels like night and day. But today got new MAF and it didnt fix. When its disconnected flutter disappears.

Have not done boost leak test. (wont flitter when maf disconnected.
Compression test was good.


Last guess of mine is:

Bad Tune.

And then I give up.

Any thoughts?
