The factroy tune begins to cut power as you approach fuel cut for a softer bounce off of the rev limiter. You can see it on most dynos of untuned Z's pretty clearly.

It can be dialed out with tuning.

Oh no, this is not at the rev limit. This "fuel cut" feeling can be felt as the engine revs from 2k on up regardless of how much throttle is applied. It comes and goes, though. I may try to schedule test drives with the tech this spring, and hopefully he can record or monitor this behavior.

@Kastley85891 what you're able to do there is very nice, and hopefully I can get it tuned will with the FI setup
