I could use some help with my tune. My setup is running perfect in all other aspects except for when I start it hot it will run totally lean for at least 10 to 15 seconds and then it will richen up and start running normal. Also on hot days when driving if I am idling in traffic it will all of a sudden start to lean out and I have to goose the throttle a few times before it will settle down. It never stalls when this happens but runs really rough, and rightfully so. When the temps outside are below say 50 degrees the car will start and idle correctly so I am thinking maybe something in the ect section but not sure. My car is procharged with slot style maf after the blower and placed just ahead of throttlebody. Thanks for any help or suggestions.
