We are close to releasing support for the 2013-2014 ATS 2.0T and 2014 CTS 2.0T and we really need an ATS 2.0T manual in here for a couple days for calibration testing.
So far we're seeing huge gains, 50+ rwhp and 60+ ft-lbs of torque on 93 octane on an otherwise stock 2.0T Auto.
if you are local (south Florida) and interested, please feel free to post up or email me. We'll dyno tune the car, and give it back to you tuned, and then provide you with a Free inTune tuner once they are released for this application.
Thanks!
