im told i need a port off my turbo to hook into my boost controller. but there isn't one there. i am also running a tial wastegate. i have a turbonetics 50psi controller if anyone can please help me set this thing up it would be great. can i drill and tap my turbo?

 

what kinda boost controller do you have? normally you just T it inline the wastegate vacuum source. If you definitely need a boost source, then like you said you can tap the turbo housing and put in a vacuum nipple.

Also, here is an easy quick solution:
