N55 has valvetronic to control engine load/air flow but I do not think many tuners fully understand how the tables work and its mostly guess and check. It makes sense why people have idle issues and part throttle issues with a lot of n55e tunes.

Your tuner seems to have ditched using valvetronic control and instead is using the throttle butterfly similar to how a n54 tune would be done.
