how effective porting the WG is ?

i want to know how effective porting the WG is?
my motor blew up on a cold night, the boost went up to 15 psi and the motor popped. i had the profec B turned all the way down.
so if i ported the wate gate will i be able to controll boost 100% using the profec B?
i have a 3 inch DP and a 3.75 MP and EX.

Porting the wastegate will help with controlling boost. Some members are able to control their boost fine with a ported WG while others are still getting boost spike/creep. Every car is different.

I went from getting about 3psi of boost creep to about 1/2 psi of boost creep after I ported the WG.

Since your car is going to be apart...why not?

Have you thought of getting 1200 CC secondaries and a power FC?

my car spikes to 15 psi on transition but it doesnt creep and the 1200 CC injectors can easily handle 15 psi.

i'm running non-seq. turbos so i'm not worried about the transition spike.
are there any other ways to controll boost creep other that porting the waste gate ( if it fails to controll boost) ?

bascially, with the midpipe, you've freed up so much air, the diameter of the wastegate is not large enough to let it all out. you have 2 choice, reduce the amount of air which can flow, or enlarge the exit point (wastegate) - which basically translates to a high flow cat, or port the wastegate.
