during acceleration. Note the boost
level during hard acceleration with
a given load. If future performance
declines, the maximum boost
pressure figures may be compared
to see if boost has decreased. Lower
boost can be caused by turbo
ducting leaks, a malfunctioning fuel
injection system, or a dirty air filter.
Maximum boost pressure settings
for the Power Stroke turbo diesel
vary considerably, due to manual
or automatic transmission options,
vehicle year and model, and altitude.
Boost readings may vary between 18
and 21 psi.
NOTE: Vehicle performance may be
erratic and improper if the module
connections are not properly cleaned.
90.
Use your pyrometer gauge to
monitor exhaust gas temperature
(EGT) in the engine. At idle, EGT will
be very low, perhaps only 300°F.
As the engine accelerates and is
under load, the EGT rises. The safe
maximum for the EGT is 1050°F.
The highest EGT occurs under
maximum load at full throttle, such
as climbing a steep grade with a
heavily laden vehicle. If the vehicle
reaches maximum EGT during these
conditions, downshift to reduce load,
or back off the throttle.
CauTIon: exceeding 1100°F can
cause engine damage.
