Checking throttle balance electronically sure puts a lot of faith in the accuracy of sensors. It was explained to me that the 10,000 mile service should include checking the throttle balance with manometers rather than electronically which essentially validates the accuracy of the sensors, but it seems that many (most?) dealerships don't do that because it's so labor-intensive.
I just had the 10k mile service done on my own Bonneville and I'm quite sure that they just used their scanner, and I'm not sure how (or if) I should address that.
