running rich?
Sup guys,
quick question since im still a newb.
I got an fc n/a and at WOT it's running low 10's AFR Now if i floor it it is like barley making power and just feels so dead. Is that due to it being so rich? Just want to make sure i dont have any other issues.
The car is geting tuned at the end of the month but just want to make sure i have all the bugs out.

Is this with a stock ECU/fuel pump/injectors? Low 10s are super rich, but I'm not sure it's rich enough to cause ignition breakup or dramatic power loss. Maybe someone else can chime in, as the richest I've ever logged is the occasional high 10, but never anything constant.
You can view a log from an S5 NA here: http://www.pocketlogger.com/images/r...o_af_stock.jpg. This engine did dip into the high 10s at high RPM.

Hmm...constant super rich, and nitrous? If it bogs on acceleration then it sounds like your cats may be melted. Lots of extra fuel in the exhaust overworks the cats, as they have to burn it (cats get cherry red on just one cylinder misfiring on a car). Add in consistent nitrous use...Put a stock fuel pump back in and check the cats, I bet they're plugged.
