Brian from Ohio recently had his completely stock 2016 ATS-V A8 tuned by a competitor who claimed the car was making 492 whp. After Tapout Tuning took a look we found that was not the case, along with a host of other issues. To start, Brian’s ATS-V was only making 435 whp, which is just 10 whp more than stock, and 57 whp less than claimed. Second, the competitor had desensitized the knock sensors, so the ECM could no longer protect the engine in case lower octane fuel was ever put in the fuel tank. Third, the competitor had disabled fuel trim learning, which takes away the ECM’s ability to correct air/fuel ratio based on feedback from the factory oxygen sensors. And finally, they didn’t understand how to properly command boost at higher engine speeds, resulting in boost, torque and horsepower curves looking like a roller coaster.
After doing a baseline run we loaded our Tapout Tune into the car. Several dyno pulls and tune adjustments later we were able to produce and increase of 50 whp! Additionally, we were able to reinstate the stock factory ECM safety features so that Brian could have all the fun he wanted without concern. Check out a comparison of the competitor’s tune (blue lines) overlaid with our Tapout Tune (red lines) in the below dyno chart.
