    I just installed an adjustable fpr to bring down my fuel pressure to the stock level. The problem is, as we bring the pressure down to where it should be, the car idles worse and worse and misfires. It eventually can't maintain the idle and just dies. The only way I can get my car to idle nicely is if the pressure is high, making it run stupid rich.

    The car is a jrsc b18c with 440cc's and hondata s300. The basemap I'm running is what JR gives for the setup, and should be running perfectly. What I mean is, I don't think it has to do with the tune.

    Any ideas?
