Default 2560r + enthuza 3+ testpipe ? boostcreep?

Almost ready to throw this setup on my car, my IWG has been ported but im wondering if its even possible with any amount of porting to keep this setup from creeping above 10psi ?

I get 0 boost creep on my 2560 (ported iwg) with 3" exhaust @ 12psi. I have a cast manifold and sg dp from begi.

I have the 2554R with a 3" custom exhaust, and an enthuza axleback, no cat. No boost creep at 9-10psi.

Pictures of port job? We can't just guess...

If any good amount of material was taken out it shouldn't creep though.

When I still ran the 2560, with porting similar to yours (maybe a little more) it was stable at 18 psi.

Before the built motor and IWG porting I ran 10 psi and had occasional creep. After the porting the WG was more stable at normal to abnormal levels of boost. This is with a Hallman manual boost controller.
