My friends at @COBB Tuning can clarify.BroDoze, please clarify COBB AP and Stg1 87+. Thanks!
Just check out the COBB Tuning posts on the forum, or their website at COBB Tuning - Performance Car Tuning | COBB Tuning
But, basically, their tunes adjust not just performance (some of them are performance) but also throttle management, which many have found makes it easier to more moderately use the gas pedal. They even have a dedicated fuel economy tune for the Ascent.
Not just is their stuff great, but their support is stellar.
