Message	On the other hand, an inertial dyno is measuring your vehicle’s ability to accelerate. In the end, it is all about who is quicker anyway, right? An inertial dynamometer is going to give you as close to ‘real-world’ analysis of your Z’s performance as possible. My only caveat to this statement is that the inertial dyno can only allow you to tune for WOT pulls. a brake dyno can allow you to tune for part throttle, such as drivability issues. I used a brake dyno to tune my "low throttle" A/F ratio. Believe it or not, it did make a difference. I say that this helped me achieve my current 23+mpg (348rwhp/11psi) daily driving setting. Again, its all about what you are tuning for. 90% of folks (or more) will get more from WOT pulls versus part throttle pulls. Thanks for the post!
