Ahh I showed the graph to someone and the first thing they said was lean, sorta stuck with me, but yes 11.5:1 is rich, which makes things HARDER?! Shit, that's bad for the cats/o2 sensors too right? I'm going to bitch at my chip tuner now.. brb.

edit: I don't really know, it's only around 5-5.5k where the engine needs a lot of fuel, if the dyno was correct in the first place.



edit #2, now I know why my mileage SUCKS with this chip
