I just realized what ACN is after reading this thread and looks like Im supposed to use that tune given I'm in Vegas.

I flashed my car with stage 1 91 fairly recently and it feels fine to me. The interesting thing is the ACN 91 shows that it is BETA.

Anyone switched from regular to ACN that can share their experiences?
