Alright guys, I've been doing lots of research on how to tune the regal's engine WITHOUT voiding the warranty. Spoke with a service rep today who told me that I could purchase a second ECU - tune it, and then put the original ECU back in whenever I need to go to the dealer. He said a replacement ECU would be about $900.00. Does anyone have any experience with this? BTW, I have a 2011 CXL Turbo T07.
