I was noticing in this past summer that my afr under most conditions in the 80-90 deg days is around 10.9-11.1. Winter in the real cold, as in below zero, it was closer to 11.3-11.4. Is that more or less the nature of the beast (because of air density change), or could I stand to lean it up a wee bit and still not be too lean in the cold? I ask this because when I throw the smaller pulley on I wanna know if i should aim for afr of 11 in the summer so I don't go to lean in the winter. Is there any settings I can play with that have to do with temperature compinsation?

I think its a0014 that takes care of that. Its a IAT VE correction mulitiplier.

Haha, are you saying this like its a bad thing? I think I'm way too new to tuning to attempt SD tuning.

Naw it is not a bad thing, personally i like running the MAF, but i am NA... You being boosted is a different story... just depends if your outflowing it from my understanding...
