We gained nearly 40 horsepower and 75 lbs of torque with a Trifecta Tune on our 2009 Chevrolet Cobalt 2.0 Turbo.
We now offer the Trifecta tune and its really a easy process to get a tune for your car! The flash is loaded from your laptop computer into the Cobalt pcm by means of a pc update cable that you simply plug into your OBD2 port and load the flash. The whole process takes about 5 minutes with no cutting, soldering, removal of your pcm, NO TOOLS neccesary.
Heres a copy of the before and after dyno chart:
