Installing an adjustable FPR with a gauge can help with troubleshooting (typically a non-issue), but primarily it's for raising fuel pressure to increase fuel flow. Injectors that hit max duty can still flow more fuel if the fuel pressure is raised. It's especially helpful with E85 due to higher flow requirements but for miatas under 300hp, it's unnecessary
@@TheAdatto honestly 300 was a conservative number. Unless you have a built motor and are shooting for 400 or already are maxing your injectors, there's no need to switch to an AFPR. The money would be a lot better invested in ID1000 injectors
Does it give me an advantage? I drive an 276hp 1.8vvt turbo. Money is no issue. I just want it to be as happy as i am.

@@loganalbritton1441 It will be the next step. I have a spare vvt engine that will be fully forged.
