Rising rate FPRs are called FMUs and are a ghetto way to go. The stock internals should be able to handle 6psi-10psi fine with a decent tune. The reason to goto something like Hondata and a bigger fuel injectors is to get safer tune. The ways that kits like the Turbonetics and Edelbrock handle fuel/timing are much safer than the old FMU approach, but not as perfect and reliable as doing a Hondata style setup. When you install any kit though, you will want to make sure that whatever fuel and timing system it comes with are actually working.
