Is there a different fuel map applied when the air conditioner is on? The reason I ask is because since the turbo was replaced, I can't turn the AC on because 1. it doesn't blow cold even though it's charged unless I'm on the highway, 2. it takes an abnormally long time for the RPMs to come back down if I let off the gas, and 3. it will make my car begin to overheat. When the turbo was replaced, a .50 trim was put on it and the charging tube was custom made (3"). I'm thinking it's running like that because the charging tube is bigger, but I'm not sure. I had someone do it that "knew what they were doing" :roll: The car does need to be tuned when I'm done with it, but I can't find anyone in my area who will even look at it. I don't feel comfortable tuning it myself because honestly, I don't know what I'm doing. :lol: So with that said, what are your suggestions with tuning? I live near Virginia Beach if that helps (i.e. you know someone who would be willing to look at it).
