This has to do with high IAT (Intake air temps) when the ECU see's higher temps it pulls timing to prevent ping ( detonation ) The only way to help prevent this I guess would be higher octane fuel or possibly a true cold air intake set up.
Basically heat = power loss.

Thanks for replying, friend.
I understand that, however, I'm not referring to different environments. Within the same environment temp, say, 80 Fahrenheit, the car will pull hard the first 30 minutes... after it gets to operating temperature, the car will have a noticeable power loss.
I don't find it too normal that one can only enjoy one's car for 30 minutes only, before it gets too hot and loses 15% power perhaps...and also the problem with throttle response... the first fifth of it has almost no response after driving the car for 30-40 minutes.
They told me it was indeed IAT and the ECU pulling timing... but I don't live in high temp places. Highest I see here is 85... and that only in direct sunlight
But whether it be 85 or 50, after driving the car for 45 minutes, it starts losing power... even if engine oil is 180-200, so far from overheating.
I figured this isn't too normal.
Worth pointing out that I don't push the car... im a calm driver... so even if im driving calmly with cool weather, after 45 minutes or so... throttle stops responding properly and car won't take off as usual... this is very evident when merging where I have to get up to speed.
