In the last 2 days I had my quick shifter light turn red on my 2024 RS660 and not work, the first day I turned it off and back on and the quick shifter started working again, today that didn’t work the red light stayed on and I couldn’t use it for the 15 minute drive to work. Am I cooked or is this a simple fix. I also don’t know if this is important but I did install the CRT exhaust and an up map tune for it last weekend.

I just picked up my 2024 RS 660 and I’m ready to slap a SC projects CRT full exhaust on. My question is most of the shops I called about installation recommended a dyno tune but I was just planning on getting the up map tune. Is the up map a suitable tune for a full exhaust?
