So if you hold the gas at a constant rpm it still bounces?

If you just BARELY hold your foot on the gas to cruise at a definite speed like 45MPH, it'll stay at 36psi. If you hit the gas ANY harder than that, it'll bounce between 31-36psi.

so you took out your fuel pressure regulator and you are wondering why it changes now?

It did it when the FPR was installed.



That thing was evil, it caused even MORE problems.

lol no graphs, just speaking from parts sales experience. Most fuel related issues we can solve with a filter. Wasnt speaking RX7 specific.

We put the fuel-pressure regulator back in...(the right way)



Didn't make a difference. :[



wtf
