2005 Mustang GT 5spd Dyno graph, in comparison to a 2004 Mustang Mach 1 (although the machs #'s look a little low)
As you can see the Mustang GT is pig rich, and with some tuning, theres definite power to be made there.
Mustang GT is the red lines
Mach 1, is the blue lines
GT seems more well tuned from the factory AF wise and the power really isn’t that different…kind of suprising
they are both rich as hell lean them out and get some more power
lean any of em out, and theres power to be made… what scares me is that Mach 1 dyno… they usually dyno higher.
