Backfiring time to time at idle

When my car is sitting their ideling, it will back fire time to time, seems to me that to much fuel is getting out? where can i adjust the air fuel ratio? My mods are downpipe, maincat, catback, drop in KNN air filter with stock boost.

Hehe, mine does the same.

I believe the response I got was replace the o2 sensor, spark plugs or put in the pre-cat back in. =P.

Also tune it if you have a PFC.

You can't without a programmable ECU or other fuel management system.

How old are your spark plugs & wires, and O2 sensor?
