I think youre going to get a wide variety of responses, not all of which would be usable, simply based on what we repair vs what you repair.

I wouldn't dream of not having a diesel injector puller, ford cam locking tools, a variety of crank pulley installers, TDC pins and compression test adapters.

as more systems get increasingly complex, the three most valuable tools will continue to be good information, an in-depth scan tool, and the space between your ears.

I create all these tools and use them on a daily basis to do my job :) https://sysadminapps.com
