It was only running 7 psi today, so that is entirely possible. Nothing will be happening until this AFPR is replaced though.

 

Here's some more detail:

The pieces I was adjusting on the AFPR were weak, and snapped apart with barely any effort. I'll probably send the AFPR to Flyin Miata and have them put new pieces on, make sure it's working correctly, etc.

Before that happened, as I was driving around, I had max fuel pressure adjusted to 98 psi, where it was supposed to be. However, shortly after it hit 98 psi, it would back itself down to about 90 psi, which coincided with the loss of power I've been feeling. Could this have been caused by a small fuel line leak somewhere?

We'll see as soon as I get this damn AFPR back on. It definitely feels like it'll be quick, though.

 

What's happening to the boost level when the fuel pressure drops? If you're getting a drop in boost, the rising rate regulator may be dropping pressure. It does work off of the boost signal ya know..

 

Boost stays at 7, doesn't drop, I'm pretty sure. No way to tell now as the AFPR is busted
