Funny, a performance enthusiast knocking another individual who enjoys performance as well. Regarding "Performance Minded Individuals", some people need a truck first and performance second so they are "ceiling limited" to start with, but that doesn't mean he cant be a performance minded individual and there is no reason to discourage somebody from spending THEIR money on THEIR likes.
Performance minded individuals like all different makes and models of cars. That kid who spends $1,000 on a set of headers for a 1996 Honda Civic and gains maybe 3 hp is still a performance enthusiast, he's just limited by his platform, due to some reason, and that's ok. That's the beauty of the auto world, doing things your own way, making your own choices, and getting your hands dirty in the process. The 19/20 Silverado platform is limited right now due to the PCM, so there really isn't a lot that can be done, performance wise, that is truly a "value" in the traditional sense. Not everybody has a designated performance car platform to work with, and I'm super glad to see that people are still trying to mod this platform, regardless of the limitations. Everyone doesn't have to own a Corvette to be considered an auto enthusiast, or to be allowed to modify a vehicle for performance. To be honest, most Corvette owners don't know their head from a hole in the ground when it comes to performance and value, and couldn't row through a 6-spd if they wanted too. Otherwise they would have purchased a Camaro to start with and saved $20K+ for mods (through 2019, the 2020 mid-engine "Vette is a game changer). Most (not all) own Corvettes as a status symbol of success, or as an image enhancer, and that's perfectly fine since it's their money and they are free spend their money however they see fit, but they are FAR from performance minded individuals.
Being a performance minded individual isn't about the car you own or the mods you do, its a mindset you have and a desire to increase a vehicles parameters outside of the manufacturers intended design.
Let him enjoy the fruits of his labor any way he chooses to and wait until your asked before starting to opine on his fiscal choices and the reasoning behind them.
