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?

does anybody have before and after pictures of this procedure?

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.
