Frequently Asked Questions

Q.Can the dealer detect the Predator/will the tune void my war-
ranty?
A. No, the Predator saves your stock tune and will allow you to 
restore the stock tune to the PCM at any time.
Q.Can I use the Predator to tune more than one car at a time?
A. No, the Predator can only tune one car at a time. In order 
to use it on another supported vehicle, you must first restore 
the stock tune to the car it is married to, which will unlock the 
Predator.  
Q.Where do I plug the tool in to the car? 
A. It plugs in under the dash in the OBDII port which can easily 
be located by looking in your DiabloSport Predator’s manual or 
you car’s manual.
Q.I am not a mechanic nor do I know a lot about cars, how hard 
is the product to install?
A.  If you can change the channels on your television you can 
install the Predator.  With the press of a few buttons and about 
3-5 minutes your selected tune will be installed.
Q.  How much horsepower will I gain? Will I lose fuel economy?
A. You will notice a significant difference in the drivability of 
your vehicle.  Average Horsepower/Torque gains are 5%-7% 
and these are real numbers.  Our gains are measured as “to the 
wheels” not to the crankshaft or to the flywheel like some of 
our competition does.  In specific vehicle applications we have 
seen Horsepower and Torque gains up to 30% to the wheels!   
Q. Everything seems too good to be true, but I am worried 
about my fuel economy.  Will I experience a decrease in fuel 
efficiency?
A.  No! As long as you drive under normal conditions and do not 
have a “lead foot” you will generally see an IMPROVEMENT in 
your fuel economy.  In specific vehicle applications we have even 
seen fuel gains up to 30%!
Q.  I know technology is changing and so are cars.  How can I be 
assured that I am getting an up to date product?

A.  DiabloSport takes every precaution necessary to ensure that 
the product you receive is updated to the most current revision 
we have.  We also offer FREE ONLINE UPDATES for all of our 
Predators.
Q.  What other features/parameters does the DiabloSport Preda-
tor offer for my Vehicle?
A.  Depending on the year, Make, Model, and fuel type, the 
diablosport predator offers a mass of adjustable parameters.
