Ok, to start off, its called AIR to FUEL ratio. A/F. If you're getting 10.5, your are more rich then you would be at 12.5 and so forth. For monitoring, a Wideband o2 sensor is what you're lookin for. Here are a couple of basic widebands that read your AFR for pretty cheap...

the lower the number the richer it is, a good wot to shoot for is the mid 11's (11.2-11.8) depending on your mods, a smaller less efficent innercooler should err on the rich side

Hey Hey
Our mods are a large intercooler the blue BOV and a CAI ans soon a 3"exhaust thats it for now.Over the winter we are going to do the bottle neck fix 12 volt fix and maybe a -6 fuel line with return.
