In case anyone was wondering, with the Walborro 255lph pump on an otherwise stock fuel system (no upgraded FPR) I passed Washington Emmisions with flying colors. This was orginally a concern of mine, since I have to get my car (California) registered in WA. I have a CAI, and wrapped Y-pipe. I thought that since the fuel pressure is raised (38psi vs 34psi stock) I might have a problem with emmisions, but that was not the case. I know in Cali however, they pop your hood, and I would have failed for having the intake, not to mention the Y-pipe. I have an AEM FPR, but the screws on my old FPR are stripped out, and my local Nissan has been taking FOREVER to get new ones in, combined with constant shatty weather here... Oh well, at least now I can register my car...
