There are those who work because it's work, and those who work because they like it and do it outside of work. I told my wife when I can retire from federal govt, I'm going to work for my local shop and work on cars...get trained as an apprentice, because that's what I like to do and learn about.I love it. Actually, I'm looking for another R430 to put in for redundancy, I do have a T130 that gets used on occasion to host the critical stuff when I'm doing maintenance on the rackmount server, and will probably get all of the VMs temporarily hosted while I move the primary server over to Server 2022/Hyper-V. I'm starving at work though, nobody I work with does in-depth tinkering at home with anything tech oritented. Just a bunch of console gamers and spec-obsessed nerds, nobody talking about what they're actually doing beyond watching MCU movies and playing whatever COD is current.
I wish I had the capacity some of the DIY tuning guys have though. Like, they're bench flashing ECUs, writing code to allow easier modification of them, all that fun junk. I feel like a monkey by comparison, I'm just utilizing guides others wrote and doing dumb stuff to suit what I want, hardly anything that's super advanced.
As for DIY tuning...at least you're starting down that path...it'll lead to more in depth trial/failure/success and comfort in the space.
