RiffRaff billet wheel vs KC billet wheel?

I'm needing to cure the surging issues I have on my 2000 down in my sig. I never had surge untuned. Once I acquired tunes I developed surge. I also figured I would rebuild the turbo along with a 360* thrust bearing upgrade while I am in there. The riffraff wheel is a 4x4 design while the kc is a 6x6. I'm not really sure what that means? Does one cure surge better than the other? I don't need the loudest sounding turbo on the block I just need a non surging turbo. It's embarrassing to have the turbo struggle while pulling a very lightweight aluminum trailer.

I had great success with the Riffraff 4/4 billet wheel when I was running my modified stock Garrett turbo. I would ask you what intake you have if it is 6637, stock, AIS, S&B, etc....

I have been running the riffraff wheel with the 6637 intake for 5 years, it fixed my surge and pulls great. I have heard good things about KC products as well, I just ordered a turbo from them. I would get whatever one is cheaper.

Yup riff raff and 6637 here and no surge with tunes. Works very well. Also not loud which was huge plus for the wife and kids.

4+4 here as well. Nice n quiet till you are around 14# but by that point the engine is usually louder as well
