Not have access to 91 octane and want to get a RaceChip for the 3.3T stinger. Are the only advantages to buying an RS or GTS model the additional tuning maps you get? From what I’ve gathered you get 5 with the S, 6 with the RS and 7 with the GTS. I’m not worried about mobile app as I am not interested in it. Any feedback would be appreciated.
