Part 3 - Mini Cooper S R53 363cc fuel injectors install and test drive

In this last part of a 3-part series, I show how to install upgraded fuel injectors on a mini cooper r53. In my case, I am using 363cc injectors and I go over that in part-1. Near the end of the video, I take the car for a test drive and show the fuel trim levels. The factory ecu is able to add or subtract up to 20% of fuel delivery by default through its fuel trim algorithm to get the engine to run at its most optimal state.
