Most ATS-V owners who have their cars tuned for higher boost run colder spark plugs. This a good idea because it helps reduce pre-detonation and the ECM’s knock retard response, which reduce ignition timing advance and horsepower. We recommend and stock NGK 6510 iridium plugs, and now have these in stock for immediate shipment. Stock ATS-V plug gap is .030 to .035″. With increased boost you’ll want to gap these at .027″ for maximum performance. Contact us today to make sure you have the proper spark plugs for the best performance on and off the track!

100 More Foot-Pounds of Torque!
We recently dyno tuned a 2016 ATS-V with intake, downpipes, mid-pipes and a competitive company’s tune. The customer had been led to believe that his car was producing 502 whp. Using the industry standard DynoJet 424x for the most precise, repeatable data, we found that his car was only producing 427 whp. Even worse was the shape of the curves, as seen in the blue lines. The boost, horsepower and torque curves each had six or seven distinct peaks. We restarted from scratch and produced a beautiful tune. Peak power increased by 50 whp and torque was up more than 100 foot-pounds at 3,500 rpm. We believe this is the proper way to tune an ATS-V and we have the documentation to show the customer what they’re getting.
Results Count
Scott started posting dyno charts on the Cadillac forum and presenting results in a different way than people were used to seeing them. Horsepower and torque were being measured on the best dynamometers available, using the industry standard SAE correction factor and proper smoothing. This made the numbers presented completely legitimate and reproducible. Air/fuel ratio and boost were also included on the charts. Most importantly, these dyno charts showed wide, flat powerbands with incredible area under the curve. People noticed, and Scott started receiving private messages and emails from other ATS-V owners asking for help. And so Tapout Tuning was created as his latest venture into the world of automotive performance.
