[MENTION=13598]Gibbo205[/MENTION] can you please explain this?
Both myself and JoshtypeX are certain that our cars are slower when it hotter.
I asked Dakota for clarification of IAT Vs spark advance as shown in the next two pics.

I've def seen IAT around the 57+ degree mark. Those super hot summer days and not much air flow it ramps up. Even before the super charger was on

Isn't this completely normal? I've never had a car (and I've had a fair few cars) that didn't feel better/more responsive in cold weather. Colder air is denser, more air allows more fuel to be added to maintain the same AFR which all means a tiny bit more power.

Yes, to an extent it is normal. What we are talking about here is a drop off of a little more than that. It's not like the car runs badly or anything. It just seems to be more of a drop-off than I would normally attribute to air conditions.

Phil, were you running an open type CAI when this was happening?
