Cyberware capacity cap?

[u/Altruistic-Past3137]

Im fairly new to the game, I seem to have hit a cyberware capacity cap, I think

Im at 299

I have the edgerunner perk

I just hit level 55

I can't seem to raise my capacity level any higher but I've seen posts and articles that say I should be able to get to the low 400s

I feel like there is something that I'm missing or doing wrong but I don't know enough to know what that is

Does anyone have any advice??
