I am having an issue where I am smelling gas in my exhaust fumes really bad. I have the 255 LPH pump, fuel pump rewire mod, and a Ralli-art AFPR. The AFPR was set to 42, and I have since turned it down to 38. I am thinking I am still running pig rich though. I have an autmeter air/fuel "light show" gauge that show me 2 bars rich when I am ideling. Any ideas on what is causing me to run so rich? Here are some other mods I have:
Evo III 16-g Ported
Evo III o2 housing
Metal Intake
Dejon Tool Upper Intercooler Pipe with 1g BOV
Silicone Hoses except for the one from the Dejon tool pipe to the throttle body (brand new factory hose).
 
Well, if you're running pig rich then you'll probably have black smoke coming out of your exhaust on heavy acceleration. If it's just rich at idle, then it's nothing major to worry about.
