Default Fuel pressure @50 wot

I just have a walbro 255 intake pump and stock wiring. It reads about 58 idle and almost down to 50 @wot. Should I worry or is that ok? Do I need to get a plug and play wire kit for it? Thnaks.....

I would think 50 psi is OK. Mine was dropping into the hi 30s & the injectors were still keeping up (but I have 60lb Motrons). You need to log your inj duty cycle @ WOT to make sure it's OK. And then compare the numbers to the link in the sticky on the PCM tuning forum. As long as you aren't exceeding 85% you are fine. (less than 15-16mS) Also look at your LTFTs & your O2s (a/f) as they will tell you if the PCM is adjusting properly.

IF you do find a problem, you can get the p-n-p harness & add a Boost-a-pump, or get a regulator.
