This is a custom performance
tune done by Trifecta Performance. The cable needed to install this tune is sold separately.
Select –a- tune: Allows you
to drive in “stock” mode with lower boost levels and lower power for day to day
driving. At the touch of a button you can enable the high boost “race” tune.
No-Lift-Shift: Just like on
the Cobalt SS Turbocharged. Keep your foot to the floor as you shift, just like
a power shift. This keeps you in fill boost between gears.
You will receive the tune
file via email and a link to download free software to upload the tune to your
car. Once the tune is uploaded, you will need to data log the car by driving
it. Once you have created a data log file, you will need to email that log file
to us. Trifecta will analyze the log file and send a new tune file, if need,
that has been updated with any changes to air fuel ratio, boost levels, timing,
etc. We will repeat this process until the car is dialed in.
