C21BILL - I do not have one. Benefits to a regular car of increase in throttle response maybe desirable, especially those who like to drive more dynamically or more aggressively (not to be confused with driving unsafely). But most modern sports cars or sports sedans or even luxury sedans already have this functionality. So my question is - would there be a need to drive the 11,000 lb. AI in the same dynamic or aggressive manner as cars 1/4 of the AI weight? I am pretty happy with the throttle response in mine. But I not sure if my 2017 Sprinter throttle response curve is mapped differently than your 2014, such that your unit can benefit from it?
Theoretically, modifying the throttle response does not affect fuel economy because you are not tuning the hp/torque curve differently. BUT, the modification ultimately changes one's driving style/habits to the more spirited driving style which will ultimately decrease your mpg.
