I personally see no need for the boost scramble on the stock block, but it's good to have for the future.
So I'm assuming it is running on GTM's tune, which is what I have. Do you plan to get a new tune? If so, update the throttle table with an aggressive (keep stock table for one of the maps for safer driving), and change the cooling fan settings so it kick in sooner.
BTW, I bought the TIAL wastegates from VQStryker
It has the 8 PSI springs, but I'm going to switch them out to 5 PSI springs to be safe. Sitting in the garage at the moment...
