Stg 2 OF on stock 2017 with auto

[22R]

So I have read a few time s that the newer stock exhaust manifold is pretty decent. So how would flashing to stg 2 affect the car versus stage 1 ? Please keep in mind I am new to the whole tuning thing so I am just wondering.


Thanks,

Stage 2 is for aftermarket header. 2+ is for no cat header. And I believe only the 2017 MT has a new header not the auto. If you have high quality and high octane fuel you could try stage 2 a little more aggressive then stage 1. Just log your AFR IAM knock correction and LTFT / STFT. If it runs fine then use it if you want.
