I've been living in GA for a year now, im originally from rhode island....the weather up north east was much denser and much much cooler in the summer and winter compare to down here....i notice the difference on the numbers people were hitting at the track with way much better performance upgrades then my car, back up north at the New England Race Track in NH, i ran 2 times and hit 14.0 and 14.1 on my stock gsr swap in a 93 eg......and b16 swaps were doing mid 14's to high 14's....honest to god too........so yeah depending on the weather and enviorment u live in it really matters...why u think people put ice bags and use nos to spray down on their car intake manifold or intercooler....to keep it from being too hot...and to give it that instinct cool air flow for their vehicles to perform....one thing...earlier morning like at 4 or 5 in the morning....before the heat starts to rise, warm your car and take it out for a spin and compare the difference when in the afternoon......

(not just bc colder asphalt means less traction either)

On a highly tuned vehicle some adjustments may need to be made to get full benefit but on a relatively stock one that's the job of the air flow/air temp/air pressure sensors and it should adjust for it just fine...
