hey guys, just installed my VWR intake in my APR stage 1 R, and i get a pretty strong flutter sound when at speed and throughout the rev range, and i get a cut of power at around 6,000 RPM.

is this just the computer re-adjusting?

DV problem?

install went down without a hitch.


thanks in advance for our response !

Flutter with foot all the way down? Or when you release..?

Same thing here. Not flutter though,,, I don't think.
Kinda feels like its hitting the rev limiter about 800 rpm to soon.

Whats your fuel trims look like?
Would love to see your data logs!

Post them up when you get them!

Wondering if my top end cut is due to the high fuel trims of the VWR intake. (Causing throttle cut)

It's a lite flutter throughout the power band, and if I let off at or just before redline, it jolts forward and cuts power
