The car was runnig fine at 18psi with the AF at 11.4-11.5 and now all of a sudden its leaning out to 12.0-12.2. What could cause this. Could it be the 100 degree weather or something else. There are almost brand new Apex'i 550cc injectors so i doubt that they are going bad.

Damn dude hahaha running at 18PSI sounds like you getting hang of that profec. Anyways to your answer, yes that is definitely a factor. Ambient temperature obviously makes a huge difference in AF. You can test this by trying to drive it at early in the morning or late at night when temps comes down and then test it against boosting in the afternoon.
