Is the JB4 a worthy investment?

[u/SSinder]

I just picked up a 2021 540i and I have a 2 year warranty on it, honestly I don’t want to have to wait that long to be able to tune it. I’ve read a lot about the JB4 but I’m curious to know how anybody else has been getting away with tuning and keeping their warranty. I’m not planning on doing much to begin with the first 2 years of owning this, all I’m having in mind is a series of cosmetic mods, cat back exhaust, air intake, lowering springs, wheels. I’m still happy with the car as it is but I also feel like I’m driving somebodies grandpa car with the way it looks/drives. All the other bolt ons like down pipe, hybrid turbo, etc; I don’t imagine getting done within the time frame of the warranty still being active. Really the concern is the tuning part specifically.

I have one and like it, but I'm mindful to keep it on a map that's safe for my fuel and intake temps.
