I promise you that I have not seen even a 6-7 degree drop either. I have had these new brinks for nearly a year, and have a lot of data logs. I am modded. Intake is the SDG Max-Effort billet with their max effort billet bearing plate. Again, I got these bricks at a very deep discount.If I deciphered it right its only 6-7 deg drop for a modded car. If adding a hx AND the bricks you get more of a drop. But I already have a 3.5 hx so 6-7 deg isnt worth $1700, not even close.
