Two years ago I had the MM engine dynoed. results: 487 RWHP & 494 torque. No mods in between then and today when I had another shop dyno the MM. Results: 481 RWHP, about the same, and Torqued 431, down 63 #feet. Both were Dynojets.
What might cause Torque drop? Bad tranny, bad TC, bad fuel delivery? Any thoughts?
