Okay, so i have been experiancing some BPV flutter. The thing is its not between shifts. its when coasting it gears 1st and 2nd at low speed. It flutters as the exhaust is popping. (catless)

I have a Dejon SRI. Any idea why its doing this and if its hurtful to the turbo?

Thanks in advance, Andrew.

 

Any ideas?

 

Its normal, the stock intake will baffle the sound while the metal intake won't.

 

i get a little also cruising randomly

It is normal....mine does the same thing and has for as long as I've had an intake. Could also be heard with the airbox mod.

 

Ive had it once or twice myself. You can hear it when your almost around 0psi or 0 vac right? like right at the 0 mark on the boost guage. Its like the BPV doesnt know if it should open or close. I personally dont think its a problem nor is it bad on the turbo

 

I had the same experience this weekend. hadn't heard it in awhile. Stock intake and stock air filter as well.

 

Check your stock bpv rubber just in case...
