Yes that is correct. Tune for performance and not temperature.

Here's me thinking....

Hot ambient temp is kinda pain in the b-tt because it makes your engine life harder in two ways.

1. Hot air contains LESS oxygen then cold air. LESS oxygen is NOT good for your engine since it will use/need less fuel = BAD PERFORMANCE.
2. Hot air cools off your engine LESS then cold air.


You can compensate the higher temp (#2) with more fuel for better cooling but then you collide with (#1) and you get a rich running engine with bad performance.
To sum it up = Hot ambient temperature is ALWAYS bad for your engine, in many different ways, and like many have said before, tune for performance and not temperature.
