Okay, I took the Expedition in and had them do the PCM reprogram per the TSB. They didn't charge me for it since they were doing some other work and since they've caused me a lot of grief for past problems that still haven't been solved.
Anyway, there is a definite difference with the new program. The Expedition runs much better in hot weather. I could definitely tell a difference while towing my boat during some 95 degree weather.
I wasn't going to do the PCM reprogram if they were going to charge me since I am planning on getting a SuperChips Micro Tuner 1715. But since it was free, it was well worth it.
