he shouldn't be..
You miss understand. Yes.. cold air is more dense and can lean you a little. It's also a much cooler air charge.
And th part you misunderstood....we'll tune my car...
I used to think this as well... but after I got a wideband it's clearly not the case. You will actually (on the stock tune which is setup to be super safe) run more rich in the cold. The MAF sees the air as being more dense and adds fuel accordingly.
You will lean out in the cold if you are maxing your injectors though. They might not be able to keep up with the demand that they otherwise would have when more air is coming in. But I'm not sure if you're anywhere near that point.
