I know for a fact the 8 speeds have lots of potential, the whole is350 platform does.

I just bought a '23 350 RWD. I've moved from a '13 MK6 Golf-R (stage2+ tune), which I still have. I'll be looking for a tranny tune, but in no hurry. The software on my R has been rock solid for years now, so of course I'd want that for the IS.
Good luck with your tranny, and keep this thread updated as you get more time on the tune. The whole world is watching.![Cool](https://www.clublexus.com/forums/images/smilies/cool.gif)

But tell me, what fact do you have about the potential of this transmission? I'm interested to know, because a more sporty tune, within safe margins, can be the icing on the cake for an otherwise great car.
Tia,

these 8 speed transmissions can handle a hefty amount of power to the wheels, 9mesh a twin-turbo build making 900+ to the crank and around 750whp is still running the stock transmission, he also has tuned his transmissions and we see much sharper and quicker shifts.

I'd love to swap in the 4.08 diff from the 2IS, it would bring the 3IS350's 0-60 down quite a bit, but the transmission shift points become out of whack. If someone could tune the TCU to correct that...
