Every once in a while at the track, I'll adjust my fuel pressure to fine-tune the car.
Today I adjusted the fuel pressure up 2 psi and after a handful of runs I decided to bump it up a bit more. When I went to adjust it, I discovered the pressure was higher (4-6 psi) than when I had previously set it! So I left it be.
Hmmm... fuel pump going wacky? Need a new fuel pressure regulator? Funny fuel pressure guage?
