2013+ Cadillac ATS 2.0T Stage 1 Performance Tune

The RPM-Motorsports Stage 1 Performance Tune for the 2013 and Newer Cadillac ATS 2.0T is designed to work with completely stock cars. More gains can be found by combining our custom tune with bolt-on modifications.

Stage 1 Tune: 300 horsepower & 330 torque
Stock Tune: 272 horsepower & 295 torque

  • Speed Limiter Removed
  • Electronic Torque Restrictions Removed
  • Timing Calibrated for Premium Grade Fuel. (91+ octane required)
  • Low end torque and fuel economy improved by optimizing timing and boost
  • Upper RPM powerband substantially increased to make better use of the 7,000rpm rev limit.
  • Max Boost level raised to 21 – 22.5 psi (Stock boost is 16 – 17.5 psi)
  • Optimized Air/Fuel Ratio for increased boost levels
  • Increased Fuel Rail Pressure at higher RPMs
  • Virtually no turbo lag – Immediate throttle response
  • No substantial noise increase over stock tuning
  • Fan speeds increased to keep engine temperatures cooler
  • Emissions Compliant



2013+ Cadillac ATS 2.0T Stage 1 ECU Tune


The 2013 and newer Cadillac ATS 2.0T comes equipped with the totally new LTG motor. This is not the same as the outgoing engine in terms of performance or capability. On paper the LTG engine looks like a real winner, but it doesn’t take long behind the wheel to realize that the factory setup just isn’t adequate for much more than putting around town like an old lady.

While we worked with our beta testing cars we noticed that the stock tune had a tendency to close the throttle during WOT, which resulted in sporadic performance and unpredictable passing power. One second you are foot to the floor, throttle wide open, and the next moment the car decides that the throttle body should be partially closed. You might experience the feeling as more of a flat spot in the power curve, but it’s not consistent and it’s definitely not good for performance. What is actually happening here it that the ECU is sensing a slight amount more airflow than what is predicted in the programmed airflow model, and so it reduces the throttle opening and lowers the demanded boost pressure.

With the RPM-Motorsports Stage 1 Tune we have not only cured the tune of these throttle closing issues, but have also been able to successfully command a more powerful and reliable amount of boost across ALL of the RPM range. No more spikes at 17.5-20psi, the boost comes on more rapidly along with improved power enrichment fueling that results in more torque down low. All of that peak torque would only go so far if the airflow didn’t carry onto the higher RPMs so we also raised the allowed airflow limits at higher RPMs to eliminate so much of the stock program’s power reduction, all while maintaining safe Intake Air Temperatures after the stock intercooler.

Our tunes are delivered via our proprietary and industry leading V-Tuner network.

What makes our V-tuning network different from other tuning companies:

  • Other companies require you to mail in your cars ECM, this causes downtime for you as your car can not be driven during this process.
  • Other companies use hand-held flash devices, these devices simply force a “Canned” non-vehicle specific tune file onto your cars ECM, this is dangerous for both the ECM and vehicle and can result in a dead controller not to mention the tune you are getting is not engineered specifically for your car.

Why is our V-Tuning network the best option out there:

  • Simplicity, we mail you our V-Tuner device, you plug one end into your cars OBD2 port and it connects to your homes broadband internet…push power and our device creates a digital bridge that allows our master tuners to “Live” tune your car as if they were standing next to it!
  • We begin with your factory ECM file and Operating System, this allows us to back this up in case it is needed later and it also is safer as we are writing a file that is specific to your car.
  • NO CANNED TUNES HERE: All our tunes are specifically written for your vehicle taking into consideration your “Bolt-on” modifications as to maximize the tunes efficiency and HP/TQ.
  • We do all the work… Plug in, connect, and sit back letting us do all the work… it can’t be simpler!
  • Once finished you will return the V-tuner device… No hassle, no deposits, It easy!
