IMPORTANT PLEASE READ
TUNE INFORMATION
DiabloSport Performance - For stock to mildly modified applica-
tions - NOT FOR USE WITH SMALLER UPPER AND/OR LARGER
DIAMETER LOWER PULLEY APPLICATIONS
AFTERMARKET PARTS
Use of the DiabloSport Predator with aftermarket products is
at the owners risk; some aftermarket products create rich or
lean conditions based on design by the products manufacturer.
It is impossible to test every possible product so please proceed
with caution when using any product related to adding airflow
like throttle bodies, filters and cold air intake kits or boost in
the form of pulleys, or blower upgrades, changes in exhaust
systems or exhaust components, even rear end gear changes
(which make rate of acceleration changes can affect air fuel
ratio). Customers with these modifications may need a custom
tune from Diablosport or one of its CMR dealers. DiabloSport
recommends the use of a dyno and air fuel meter to monitor
data when adding aftermarket products to make the proper
tune changes with Predator.
*Premium grade unleaded fuel must be used for all PREDA-
TOR applications; AMOCO, MOBIL, SUNOCO fuels are recom-
mended.

port Performance Tune, and keep them closed until the process
is complete.
• Do not activate any electrical accessories while installing
the DiabloSport Performance Tune. Ensure that there are no

Installing the Diablosport
Performance Tune

Installing the Performance Tune
Predator contains several predefined DiabloSport Tunes. These
are thoroughly tested and approved by DiabloSport. You have a
choice of either installing the DiabloSport Tune “as-is” into your
vehicle, or customizing it to your personal taste.
If you are satisfied with your factory tuned vehicle and only
have a desire to modify a parameter or two (example: change
gear ratio), you might want to read the chapter ‘Customizing
the Factory Tune’.
Before you install any tune into your vehicle, when you use
the Predator for the first time, it will read the Original Factory
Tune out of your vehicle and permanently store it in its memory.
This process takes a minute or two. For safety reasons, there
is no way to overwrite this backup and therefore the Predator
becomes ‘married’ to, and only to, your vehicle until original
backup is restored.
If there is ever a need to send the Predator back to DiabloSport,
for any reason, the Original Backup must be put back into your
vehicle, as described in the section Reinstalling the Original
Factory Backup’, otherwise your Predator will not be accepted
back by the reseller. To find out, which tune was last written to
your vehicle, go to ‘Predator Options / Show Last Tune Written’
in the Predator.
