I've had my setup on my car for a few months now and had it tuned and all that good stuff but have had a flutter issue. The car will do fine when I go through the gears if it has a good load on the motor. Holds 10psi with no problems. I have the flutter issue when the car is in a higher gear and I try to speed up and not gear down. It will flutter until it hits full boost and then it will be rock steady. Kinda like if I did a 20mph pull in 3rd it would happen. It sounds like ch ch ch ch ch ch when it does happen.

Any help with this would be awesome.

 

you're on the compressor wheels surge line

 

How would I go about fixing this?

Edit: Wait I think I get it. In those gears its below the line on the compressor map? Correct? I guess I need to research that stuff.

 

can't, well you can...but it requires a machine shop and will cost more than buying a turbo with a better surge line

 

Hmm. Thanks for the help. That's the first solid answer I have gotten from anyone about what it could be.
