I would if I needed to know the exact numbers my X is putting out, but for the minimal amount of gains I already expect, I dont exactly see a point. At most, I'd be 10-14hp and 12-18ft.lbs more than stock. Even if it were slightly less, I wouldn't be disappointed. Its clear the 3.0i version of the e53 lacks power upgrades, aside from a supercharger kit.

Maybe if dyno runs were cheap/free and nearby I'd throw it on to see the numbers.
