Are ECUtek and Uprev tunes reversible

Very true. I know that they won't check for anything like that but if I have a sensor failure where they need to test monitors or run some sort of diagnostic, I wonder if that could cause a red flag. I still have a lot of warranty left and I'd rather not void it if at all possible.
