This was a remote dyno tune on a 2017 ATS-V with flex fuel and methanol injection.  The customer had switched from a competitor to Tapout. Check out how this exceptionally broad powerband maintains 550 whp and/or 550 wtq all the way from 3,200 to 6,900 rpm.  We weren’t surprised when he said, ‘I’ve never felt so much linear, smooth power on this car before’.

This 2016 ATS-V M6 has aftermarket intake and exhaust mods.  He was running 93-octane fuel and that sweet Tapout tune. Numbers were a little higher than usual, since this dyno used a load cell. Load cells increase load on the car, helping the turbos to generate boost like they do on the street.

We remote tuned this 2017 ATS-V with 93-octane fuel and no performance modifications.  What a beautiful powerband!

This 2016 ATS-V has Brisk spark plugs with plenty of dielectric grease, and is running on 93-octane.  Baseline run 0 was 430 whp, for a net gain from the Tapout tune of 69 whp.

This 2016 ATS-V has methanol injection, valvesprings, spark plugs and octane booster.  OEM intake and catalytic converters are still in place, but have been modified for improved performance.  Note that it was 103 degrees during this run, and the dyno was having difficulty maintaining a tachometer signal in the Texas heat.
