Running really lean, common fixes?
I threw my car on the dyno the other day and it dips below 11.5 AFR between 5-5.5k, I don't understand what the problem is. That's probably about 10 extra hp/torque just sitting there if I can solve that problem, and I really don't want to fuck up my head gasket either (that's REALLY lean, trust me..)
It has modified/flashed ECU upgrades, the shark injector I used is coded with dyno-tested software, so it can't be the chip.
I'm thinking fuel filter maybe?

Lean that out a little, that's good for a few HP if you're up in the 11.5:1 range..
The program you got was probably tuned for a car with a different setup or more mods..

Re: Running really lean, common fixes?
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
