We just recently purchased a 2018 zforce 800 and want to run the rjwc exhaust and says tuner is highly recommended and I 100% agree, but my question is we have the factory 1 year warranty plus we also purchased the additional 5 years, what I am wondering is if we have to take this unit in I can switch the muffler back to stock, but does anyone know how the "plug and play" tuner connects to the unit, is there a stock mode I can set it at and then "unplug and play" so I can bring it in and not have the "tattle tale" code embedded in ecm and void warranty ?
Thanks in advance
