My mate has a 4wd cossie. Totally standard bar a NMS Gunship chip and an aftermarket exhaust.

Is it possible to make it chatter or flutter?

I know that this is not caused by the wastegate but the air rushing back on to the turbo blades when the turbo stalls.

It still runs the standard airbox.

Any ideas?

Many thanks.

I have a group a K&N cone filter and it does not do it.
Need to blank off dump valve or plug vac pipe to it.

Cone filter and 500 cooler makes a difference , mines has a flump valve too and i get the best of both worlds , its mad loud for some reason

The rs 500 cooler helps a great deal with chatter, im the same as rab, dump valve and a bad ass group a k&n filter, cant beat it

My chattering scares pedestrians hundreds of meters away, running RS500 I/C and a metal mesh cone filter, and the old broom handle where the dump valve was, it's LOUD.

Does it really mess the turbo up?
I had chattering on my cossie managed S1 for ages and it never effected the turbo.

Got a massive foam filter on mine, stage 1 and it chatters and the dump valve is great as well.

For some reason I thought you got one or the other - either chatter or dump valve so was really suprised when picked up my new motor and had both. I loved it!
