i had nasty creep for awhile. i ended up porting a 2g o2 housing and removing the divider between the wastgate outlet and turbine outlet on the o2 housing. this helped greatly, but didn't fix it. i then ripped off the turbo ported the turbine inlet spent most time on the area going into the wastegate hole ( taking out the sharp bend and making a smoother transition) as well as slightly enlarging the hole itself. doing that along with removing the step in the exh. mani. and port matching it all togethar killed the creep. took some time, but well worth it. this was on a 14b in a 2g with the stock wastgate flapper and 3in dp w/ no cat.
