    My Trinity and PCM will be arriving soon and was wondering if when I install the new tune, will I lose the other drive modes? Will the black key,ECO and valet mode still work? How does the PCM know that I want the tune on full power (700+ hp) and not the other drive modes? A little help, thanks!
