All MapTun USA upgrades, from Stage 1 and up, are rolling road tested on a static dyno. Static dyno testing is the method used by automobile manufacturers, allowing torque and horsepower measurement while at the same time being able to monitor that pressure readings, oxygen sensor values and exhaust gas temperatures are kept within safe limits. To achieve this the output is measured every 500 rpm for a period of at least 10 seconds.

Depending on vehicle model and year and the required power level, we make various types
of hardware modifications.
To reach a certain power level on Trionic 7.7 cars it is necessary to make changes to the fuel and hardware system in order to keep the exhaust temperature within safe limits. Other modifications such as larger diameter exhaust system, free-flowing catalyst and larger turbochargers will allow the engine to flow larger volumes of air and reduce backpressure.
These modifications then allow us to safely extract even higher levels of power and improve drivability.

The latest versions of Saab's proprietary Engine Management System, Trionic 7 and 8, are by far the most advanced engine management systems within the automotive industry.

Modifying Trionic 7 and Trionic 8 cars requires a different level of expertise than that required for tuning of earlier Trionic vehicles. One of the most important aspects of modern car tuning is to know and understand every specific information table inside the flash memory of the Engine Control Unit (ECU). To find and control all of those tables it takes highly sophisticated software.

We are proud to say that our Trionic Tuning Tool is developed in-house by one of our own engineers. It has auto detection on every single parameter in the Trionic software and thus enables us to view and edit all values within the software.The MapTun Trionic Tuning Tool is one of the key elements that allows us to perform real and safe engine tuning in all Trionic Saabs from 1993 to 2007.
