So ive had my swap completed for quite some time and its always ran overly rich. A little background, Its a 94 with an ST-185 3SGTE swap, stock boost, and 3inch exhaust all the way back. Its getting around 15-18 mpg. My question is could this be due to the Walbro 255 fuel pump with the stock fuel pressure regulator. I bought an adjustable AEM FPR but never installed it because i was told it was unnecessary. Any ideas?
