Are there any DTC's (codes) thrown ... like Code P0299 or P2263
Also - probably not applicable but fyi ....
6.0 Enhanced PCM Calibrations:
Some 6.0 F-Series and Excursions may exhibit a low power, low boost condition which clears when cycling the key off and restarting. This may occur while driving or after start-up. Other symptoms may include false cooling fan code P0528, and/or no or slow throttle response when engaging the TorqShift automatic transmission in gear. These symptoms may or may not become apparant after having the recall 03B06 performed prior to the end of May. The enhanced calibrations are available only with WDS versions 24.11 or later. Trucks that have had 03B06 done will only have PCM and TCM updates. Those which have not had the recall done will get PCM, FICM and TCM updates.
Broadcast Message 0356/SSM #16839.

Had the same problem with my truck. Took it to the dealer and they found that the crossover pipes were plugged solid with soot. They replaced the pipe, MAP sensor tubes, cleaned the turbo and reflashed the ECU, TCM, & FICM.
