EVOMSit Tune Stages:


EVOMSit is fanatically obsessed with achieving ultimate perfection with our performance engine software. Our analytical tuning methods combined with methodical testing procedures, state of the art equipment and unmatched mechanical intelligence are fused together to create the ULTIMATE aftermarket performance software.

Developed on in-house vehicles and proven through over more than a decade and hundreds of thousands of miles of real world use, EVOMSit software is extremely well-tested and proven to provide a substantial and reliable increase in performance to the 957 Turbo and Turbo S. In addition to power, throttle response and driveability at low RPM is improved--a substantial weakness in the stock calibration. Combine with intake system upgrades such as the V-Flow Intake and exhaust upgrades, and EVOMSit software is the basis for transforming your Cayenne into something that rivals modern luxury SUVs in capability.

EVOMSit software now includes the TUNEit OBDII Flash Tool, giving users the ability to install their own tune, switch between multiple programs (*extra cost for multiple files), and flash back to stock on their own. Upon purchasing EVOMSit software, a TUNEit tool is shipped out. Once received, the tool is used to read off the OEM software ID which is sent to EVOMS along with a list of upgrades and fuel so a purpose-built file can be created. The tuned file is sent back within 24-48hr, to be loaded to the TUNEit tool and flashed to the car.

Please note the different power gains and parts needed for each performance stage.
