Lean or rich is obviously very subjective but I've found these to run better track times slightly on the richer side.Were the dyno pulls during tuning? They way you describe it they were all just back to back for numbers. Mixing some meth would help iats but then fueling needs to compensate for being richer. My tuner said coyotes care a lot about being rich as far as peak power goes. They aren't like an ls that can be quite happy rich up top. Some amount of richness is good but not a lot. We try to hit like 1 or 2% taking out fuel on the short term trims. Also where is the nozzle or nozzles feeding the meth?
