Yes, its worth the investment: $70 for the Neck, $30-50 to have it welded on and about 2-4 Hours of handwork.
30 HP is at high boost (big turbo, injectors) on a stock GN its worth maybe 20 HP max, because you will run out of injector/turbo.
It is worth about 1.5 to 2 psi without touching the wastegate.

Is that detonation free though? It might give you 2psi but wouldn't you have to turn the boost down just that much?
My TTA can run 17psi of boost at 0 KR. If I did this mod and no other change, I should be able to run 18.5-19psi of boost 0 KR if I read what you are saying correctly.
Thanks
