If you have HFC subtract about .8 from your tailpipe sniffer, even then you are way lean. Also, the downward jumps you are seeing are possibly from knock over 5 counts and it will get worse! Get that thing tuned or get an email flash from a good vendor on here for minimal money. Also DL Evoscan or Mitsulogger and log that thing STAT! You are not even close to the right track and need to get your car fixed ASAP.

Thanks for being so ignorant. If you install a conical filter, it will very likely throw off your MAF readings. That in turn, will make your ECU think there is a different load on the engine and use a different part of your fuel map. That, plus the agressive timing the stock ECU has, will make you run lean.
