What is this wastegate porting?

Basically they just enlarge the wastegate hole so that more air can bypass the exhaust wheel. Gives the ability to better control boost in higher HP applications, where there is significantly more air passing through the turbo than the stock CT26 was intended to handle. If it is worth it, thats another topic, but in most cases the CT26 isn't capable of supporting the need for this. The CT27, however, might be able to make use of it.

hehe mike, got you curious?? :hehe:
i was talking to ken and arron from ATS racing about boost creep with my 5sfte setup (ct-27, 3"dp..ect) and it holding low boost, they(ken and arron) agree that porting the wastegate is a good option for me, if for nothing more than a little more protection against creep...seems worth it to me for the price (75$)...any thoughts, guys? :givesafuc :igiveafuc :bigthumbu

And for a CT20B which i have is it going to help or hinder performance?

It will help. Boost should respond quicker and there should be no creep/overshoot.
