Are 21+ IS350 Tunable?
Dont think anyone has come out with a tune yet. I haven't seen any reputable tuners release any information on this.

It is essentially a chip tune thru OBD port...few vendors out there that have this or are marketing this. Not sure if anyone here can verify it works.
For sure no one has a ECU ReFlash Tune similar to RR Tune.

Even on my old GTI I refused to run a tune like that or even a piggyback - I did a re-flash. But, with the nautrally-aspirated engine in the 350 I don't think a piggyback really works. That's one drawback of NA power... not much you can do without modifying hardware most of the time. You can, of course, increase the rev limiter on these engines relatively safely, which gives you more "area under the curve", i.e. more time spent near peak power.
Re-flashes are typically done through the OBD port, so maybe that's it? Do you have an example vendor?

Yeah that looks like a straight-up fake product. There have been countless videos exposing these "chips". Anything that costs less than $100 and is called a "chip", other than a reputable company like RaceChip, for instance, is more than likely scamming people.

D3 Apparently has one for the 2018+. No first hand with it, but there are a handful of people on here that have it. https://d3performance.net/index.php/...ormance-tuner/
