define big power. For a road car, able to go from 300bhp to the near 490bhp on stock turbos, or 6xxbhp on aftermarket turbos without taking the engine apart this is huge power imo for stock internals.
If you check audi world, on unitronic webpage, you dont see any doubling power on stock internals.

The O2 sensors only measure across the whole bank so one could easily go a bit lean without throwing your AFR readings off much in a log, especially if the other cylinders compensated.

right O2, I saw a lot of post on that, but on other platform people get rid of this issue using 90° elbow tube to keep the o2 away from flame/excessive heat and still have good reading, and I never saw any discussion on e90post about this solution.
is it because it's been tested and has no effect? or nobody tried.
very popular on audi/vw engines.
something like this (an no this is not for space in that case, but really to avoid O2 get destroyed or check engine code)
