WTF? is this for real?

the only modification that your ecu does really is ignition timing (usually retarding due to faulty knock sensors or pinging is actually happening) or air fuel ratio

how it does this is through the 02 sensor, if too much oxygen is detected in the exhaust gasses it will richen the fuel mixture to compensate (if it can... it depends on what is wrong) or if it detects not enough oxygen it will back off the fueling to compensate

the ecu doesn't really know what mods you have or are doing to it, all i can see is extra air in which case it will richen where needed

you do not lose power by doing mods, else why would people mod their cars?

and CHIPS ARE RUBBISH!
