I'm reminded of a '90s BBC doc on John Coltrane in which his aunt related how he once told Miles Davis that once he got going he didn't know how to stop, and Miles said, "How about you start by taking that motherf***er out of your mouth?"

Why do you need "constant evolution"? If it's exhausting to you, just stop.

I have a slightly hot-rodded SC, including EFI. Fortunately the PO did all the work to get it tuned and dialed in, and I haven't touched it in eight years. As with any old car there's always a list of things you want to change or improve, but I love the car as it is at any given moment, so if I don't feel like messing with it yet I just dont, until I do.
