Thats why you normally dont port the exhaust ports/manifold on a diesel unless you have a lot more things going to it lol.

Also i agree, gluing the 2nd turbo on the back of my small turbo wasnt really worth the work/money, but i did gain 5rwhp and 75rwtq lol. Also cleaned up the exhaust, added a few mpg, and gave me some interstate power back
Those gains are worth it in my book. Out of curiosity how much did you end up spending?
