I have a slowboy racing 02 housing with the divider milled out... Turbo is a EVOIII. I got it because it was suppose to help boost creep but it didn't... How bad do you think it's hurting performance because my car isn't as fast as it should be...and not sure if my spool is all there...

Wondering if anyone had one of these and upgraded to something differernt. My down pipe is a rsr, which is close to a Apexi N1 I guess. Thanks.

Boost creep is cured by properly porting the the entryway to the wastegate passage. An O2 housing with the divider milled out (first I've heard of this even being offered WTF) or an O2 dump is not going to help. I've heard that PTEs have the divider cut on the turbine housing but this is due to a poorly designed WG outlet.

I'd send it back and get your money back as that was a stupid remedy for them to suggest :notgood:
