But if the IC part# is the same, then it should work, or very good chance.Most likey - but as the OP has questioned - we’re now in almost June 2018 and there’s really nothing avail for the 2018’s in CAI or tunes, and these S550’s have been in public possession prior to Jan 2018.
No one has confirmed if the 2015-2017 aftermarket IC’s will even fit a 2018, because the front clip has changed; so one would think someone would have test fitted an IC to a 2018 by now...
Tune is going to take a while, it took a while in 2015 to, depending on what has been changed in ECU.
