I know my fuel pressure is to high,, its at 48PSI at idle with 800cc greddy injectors..
the guy who had the motor before me said the screw on the top of the aem FPR came lose so they just put it back at a safe level???
A friend who knows alot about this kind of stuff told me to lower it to arround 40PSI,,,,,

should I put it lower or leave it at that?

Is it tuned or anything? Cause I am running about 50psi at idle (60 WOT). The fuel pressure isn't that big of deal unless its like 90+psi haha. If you're car is tuned for 48 then I wouldn't worry about it.

I don't see a problem then. If there was a problem like that, then I don't think that Hondata would post on their site that you should set fuel pressure to 60psi and then tune. Now I could see things maybe happening at like 80psi, although it has been done over and over...but I wouldn't really feel to comfy about doing it haha.
