The stock FPR isn't a rising rate, and you don't want a rising rate. They use rising rate FPR's on NA cars that have been converted to forced induction (turbo/supercharger). Since our ECU already has all of the info it needs to add the correct amount of fuel based on the input it's receiving from it's various sensors, all you need to do is give the fuel injectors 36psi static pressure and everything should be OK. If you use a rising rate FPR, your AFR's will get horribly rich as boost pressure increases.
