in the 90's i had a Z/28, my boss and his boss both had Vettes but all three had the same engine my boss bought a program that we loaded onto a LT and when you plugged it into the car, you could see what the motor was doing in realtime... the passenger could tweak parameters while on the road
it was slick as sh!t, but voided all the warranties if anything ever happened
warranty smoranty
I’ll bet Y’All had already voided that long before the “adjustments”
