Please read through the entire manual before installing a tune in your
vehicle. Failure to follow instructions can result in a damaged or disabled
PCM (Powertrain Control Module).
User must ensure that the factory “stock” tune is in the vehicle’s PCM before
installing the DiabloSport tune. GM dealer re-flashes are considered stock
factory tunes.
Serious engine damage will occur if the Predator tune is installed over a
non-factory/aftermarket performance tune. Predator tunes cannot be used
in conjunction with other tuning devices such as chips or plug-in modules of
any kind.
Do not perform any operations on Predator (expect live data diagnostics)
while vehicle is running. The vehicle must be parked, and the engine OFF.
