That is great confirmation, thanks for letting me know you installed a Boost T also.
Joey was very conservative with this kit. And, as he has said before, if you go beyond the original kit, it is on you, the owner, not on him.
I agree that the Boost T is the way to go. I did swap to the 8.5 PSI springs first, then realized I would be better off tuning it with the Boost T. I came to that realization from the below video. Ford 300 ci inline six with a turbo kit on it. On a dino, they made 522 hp and 597 ft-lbs of torque at 13.7 PSI boost, and used a Boost T to adjust the boost up. They did have to change the wastegate springs once, so, there is not infinite adjustability upward with the Boost T.
