What? You got a tune and started to burn more.... how do you think you'll be able to claim warranty.... even if you stripped all the mods. Pretty sure a scan can tell your car was tuned....

Yeah, but could a Toyota tech even find the ECU, let alone check its contents?

Let’s not forget the very beginning of this public thread on a public website starts with, “I have a tuned 2021…”

If they can detect a tune? Would they be able to detect if you used a JB4?

If you remove after deleting any codes, odds are they would not find it. Doubt anyone would really care to spend the time digging that deep.
