i have a greddy profec type s, and my question is am i soppose to drill out the holes in the valve unit? the holes already there are very small and seems like they should be drilled, but doesnt say anything in the install guide.

 

what holes are you talking about?

 

the COM and NC holes, the ones that go to the waste gate and turbo housing.

need to know by tonight, tuning tomorrow.

 

the holes dont need to be large at all but it would help a ton if you took a picture. It would help show if maybe it wasnt molded properly or something along those lines
