ses code with predator performance tune, system too rich, WTF

[FEARSNO1]

got these codes today while driving 0172 and 0175 (i think) both are system too rich for bank 1 & 2. i just cleared them and they didn't come back yet, but in between gears when i first engage the clutch i feel like it's hesitating. my a/f gauge even looks like it is staying on the rich side more than normal. i datalogged with the predator (don't really know what to do with the log though) but every thing seems fine, although i have what sounds to be a slight miss if i hold the throttle at around 2k. the dealer just put new plugs in for me less than 1k miles.
any suggestions
thanks

I believe the "Performance Tune" is optimized for CAI and exhaust.

If so, it seems likely that the predator has added fuel to account for increased airflow that comes with a CAI. You list no CAI, so you're running rich. Get a 9" or bigger filter on there and you should be fine...

very good point that had crossed my mind, i do have the stock airbox cut right at the base of the metal strap that holds it. but i have yet to fork out the money for a k&n and the stock paper filter is very dirty.

If that is the case, and you're rich enough to cause a miss, you risk fouling your plugs and catalytic converters...go to the local auto parts store and spend that $50 on a K&N :beer:

Are the predator tunes that picky? Its too rich if you only have exhaust, but too lean if you have certain CAI's?

 

[FEARSNO1]

don't know but my factory paper is pretty damn dirty so it is possible, just got back from ordering a holley power shot siter(just like the k&n except they are blue, so it will match the car.

The tune isn't picky, its expecting airflow, it is a performance tune =)

Spend the 150 on a CAI. It's worth it. Your car with the stock filter isn't getting enough air, which in turn causes a rich condition. CAI should be the first mod performed on this car IMHO.
