equipment. Your dealer has the correct calibration
identified by the calibration part numbers on the
following chart and any later updates after this

Please refer to the light duty series GM BODY BUILDER BOOK for further general information regarding

vehicle modification.

When tires are changed from the original equipment
size to those adapted to off-road usage, the Engine
Control Module (ECM) must be reprogrammed to correct
the speedometer reading.

This reprogramming will also limit maximum vehicle
speed to 93 mph (150 km/h).
