I am in Dallas, Texas which is 430 feet above sea level. All of the HBP users in this area including myself saw no more than 12psi max at 7450 redline. So a 3psi gain with RS. And yeah the butt dyno definitely feels great! The numbers are heartbreakers but it definitely feels how it should.
Do you remember your stock baseline numbers and then the numbers with the ~14psi HBP setup?
