Well it is good to know that I have a good PCM calibration but would really like to know what could be causing this condition.
What has me baffeled is it acts like a switch. When the OAT/IAT is less than 80*F, i.e. 79*F, the truck runs like it has all the power in the world but when the OAT/IAT hits 80*F or goes higher, it runs like it isnt getting enough fuel and is boosting the piss out of the turbo and am just wondering if this is the PCM protecting the motor or something else causing this.
