I just spoke with one of the guys from rallysport and I told him my issues and asked about the the same FPR you mentioned wanting to know if he thought that would fix it and he thinks it is some thing else. His thoughts were if it were the FPR it would have shown on the dyno tune. He said it sounds simpler than that like a leak or a hose loose. So I guess once I get it back together it do another pressure test.
