How many here are running nitrous? I still have a new NX nitrous setup from my Honda days and I'm contemplating installing it in the Lexus. The IS F is quick but nitrous should make it a bit quicker.
If you're running nitrous, post your setup (wet/dry, single/direct port, #shot, dyno, how long you've had it, if you've had any issues at all, advice on setup, etc.). It'll help those interested to be more informed and be in a better position to decide if it's something they want to add to their car. Has anyone here with an IS F experience a catastrophic engine failure on nitrous?

I actually got lucky. They don't tend to take on stuff other than American muscle. Mostly GM. But I went in and asked a load of questions and they took on the project. Really cool guys over there.

The A/F sensor won't make any adjustments unless you squeeze at less than full throttle (also not recommended by anyone). The ECM goes into open loop at 78% throttle and ignores the A/F sensor, so it really won't know anything about how lean you are with more oxygen than standard air.

The only reason why I ask is because I know a guy who is doing this very thing on a Tundra (I know they arent the same) with great results. He started out at a very small shot (25hp) and it went retarded fat, instantly. Im talking 9.8 AFR's. The more he sprayed the leaner it got. I think he kept it conservitive at around 10.4-10.5 AFR's. He is running high 12's with a crew cab Tundra 5.7L with an intake and nitrous only.

It will likely behave the same, but I would not do this without having instantaneous A/F data visible while testing. The 2UR-GSE is a bit more complicated than the 3UR-FSE in its engine control, but fuel should not be different at all.
