the air temp map
 

i think i understand what its used for, but my question is about how to tune it. it seems like the factory doesn't use the air temp sensor as much as the haltech does. is it better to have a flatter map, like factory? or should it be bigger, or more agressive?

The compensation maps should not really be touched until you have tuned your map just right. The exception of course is if something is way off or you are having issues and trouble shooting.
