Kyle is correct... We also noticed that it's creeping! But I thought the ported O2 shoulda fixed it?

No you need a bigger flapper so the air can get out of wastegate hole versus following the nice turbine outlet hole. Porting the O2 will just help spool and if you did the flapper upgrade then it might help creep.

[Shane@DBPerformance]

Depends which part of the O2 you port. If you work on porting the wastegate channel, then you can help get rid of creep. If you make the main exhaust channel huge, then you make it easier for it to creep.

hmm..still creaping huh? That o2 housing is pretty much as ported as a 1g can get, maybe we can look into the larger flapper or a ported 2g option.

[Shane@DBPerformance]

2Gs might have a bigger wastegate channel while the 1Gs have a bigger main exhaust channel. So a ported 2G might help or an EVO 3 O2 housing. Or just do the flapper.
