Packages are now available to accommodate a customer who may wish to convert a 1986 low altitude vehicle for improved high altitude (over 4,000 feet above sea level) engine performance.
Vehicles with the low altitude package transferred to service in high altitude areas may exhibit undesirable driveability. However, the installation of a high altitude conversion package is voluntary and at the customer's expense.
The high altitude field conversion packages and procedures outlined below have been authorized on the following 1986 non-altitude equipped engine families in service at altitudes above 4,000 feet above sea level.
