So I know starting in 2020, GM firewalled the ECU’s on all their vehicles. So that means no Superchips, Cortex, or any other power programmers of any kind, and even if I had the extra cash to dyno tune it, I doubt HP Tuners would work either.
Has anyone heard of anyone is working on a programmer for the 2020+ AT4s? I know they’re powerful already, but like my dad always said, “there’s no such thing as too much horsepower.”
