I'll be honest with you... this is the first truck I've heard of that had a lean condition with a Gott's mod! I doubt updating your Evo will help because the calibrations haven't been updated in over a year anyway.
Did the jump in IAT coincide with the lean codes? If so, check for any vacuum leaks and repair as necessary.
Also, what kind of air filter are you running? Oil element (K&N style) filters have a nasty habit of contaminating the Mass Air Flow sensor and can also exhibit similar symptoms, especially the elevated IAT. Even if contamination isn't the issue, it could still be a bad MAF sensor.
Hope this helps.
