Tuner's notes
What to know about tuning the Camaro / ATS / CTS 2.0T LTG
Stock figures are for the Camaro; the ATS and CTS are rated at 268-272 hp. The stock turbo runs out of breath at high rpm and heat-soak knock retard is the main limit on pump fuel, and full E85 needs a cam with a high-pressure fuel pump lobe.

Before you order
What you need to tune your Chevrolet Camaro / ATS / CTS 2.0T LTG
An HP Tuners interface. We recommend the MPVI4. You do the reading and the flashing yourself, on your own car — our step-by-step guide covers buying and setting it up.
HP Tuners credits for the engine ECM. Reading, logging and editing are free; you only spend credits the first time you write a tune to the car. Check the exact number for your Chevrolet Camaro / ATS / CTS 2.0T LTG on HP Tuners' supported-vehicle list before you buy.
A laptop with VCM Suite. HP Tuners' software is a free download once you have an account.
Your stock file and a datalog. The stock file is what we tune and your backup; the datalog shows us what your engine is actually doing, which is what makes the first file right.
