OK me and my buddy anthony (1g also)
went to work porting my o2 housing.

everythign done and said and put back together. I still have boost creep issues, and its About the same as before. almost like it didn't help at all if any

Ok the other thing we think is the problem is the wastegate flapper.

can anyone please give us some tips onto how we can change that flapper or should we just port more?

we ported the bottem exhaust hole and the o2 hole, NOT the other top exhaust hole.

take the turbo out and port around the wastegate whole. make it nice and smooth and see what else u can do to direct air into that direction.

I think we will try that next weekend or whenever we have time, hopefully that will fix it! I don't find a vfaq or anythign to mod the flapper so I don't wanna try and screw it up :p

Would it be a Good idea to port out the turbo exhaust side on the o2?

or would that add to the boost creep problem

the bottem exhaust side we ported to about 2.5 inch hole....
