Default Request

Can someone (if they have any) post up any dyno sheets that have air/fuel ratio as well on them? Looking for bolt on cars if possible, thanks.

The car doesn't always run so rich up top. It just depends on the ECU's mood. I went back another time and the graph doesn't appear to have the dip in power up top like it did before which tells me this car is just very sensitive. See link below
