I've read that the stock setup, with the vacuum pump line, and the diverter valve, is what Ford decided was the safest setup for our engines and turbo. After getting tuned, since the stock diverter valve is reportedly not quite up to the task, I upgraded to a turbosmart 50/50. Is this still the safest setup if I still have a stock turbo and wastegate? I would love to have a cpe kit with a tial BOV, although the cost is a bit high. But if I ran that setup and used the vacuum from my symposer delete, would it make any difference? I have done a lot of searches, but this is one detail that seems to be missing from what I have found. I am hoping to gain some better understanding, and less flaming, from my question! Thanks in advance.
