Jeff brought us a completely stock 2016 ATS-V with 85,000 miles on the odometer. We installed the Purple Belt Performance Package, in addition to Mace Stage 1 valve train components. Check out how strong his powerband holds, all the way past 7,000 rpm! Jeff will certainly have a lot more fun racing now!

Way back in 2008, Bob Cook built and drive the first GM Series II/III FWD to ever hit an eight second quarter mile, running 8.95 @ 157 mph in his ’99 Grand Prix GT. 15 years later at the 2023 Cadillac Attack, Bob was behind the wheel when his 2016 ATS-V became the first to crack eights. After three days of racing, we was able to lay down an 8.97, 8.86 and then 8.77 seconds on his final pass.

Modifications include the Tapout Tuning Brown Belt Performance Package, with the turbos switched out for aftermarket units. The engine, cylinder heads and intercooler are still stock except for forged pistons and stronger fasteners. Basically this car is running the initial beta test of our future Black Belt Performance Package. It will take a while to figure out how to neatly package and produce this kit at an affordable price. Stay tuned, since all details and pricing will be announced later this year.

Tapout Tuning is the main innovator for the LF4 platform. We pride ourselves on offering the best possible parts, service and tuning.

Reed worked with our partners at Exodus Performance in Texas to install his Purple Belt Performance Package with EPA catted downpipes. We jumped online and did a remote dyno tune and the results were great, just like always. No one offers better performance packages, and no other tuner can match our beautiful powerbands!

Ken drove in from Florida to have us work some magic on his 2016 ATS-V A8. All his other cars are fast, and he didn’t want the ATS-V to be slower than his ten second Corvette or supercharged truck. Jorge installed the Purple Belt Performance Package and Scott got to work on the dyno. Final numbers were 617 peak whp and 664 wtq, using the industry standard SAE correction. We hope Ken enjoys his 1,200 mile drive back home!

Dane purchased all the ingredients for our unmatched Brown Belt Performance Package, and did an excellent job installing everything himself. The last time he was here, he had just installed the Mace Stage 1 springs and retainers, but not the cams. This time he was back after having installed the Mace Stage 1 camshafts as well. He made the trip back to our shop from Illinois, and we got to work on our DynoJet. Once again, Caddy Issues turbos delivered, making 763 peak whp at 29 pounds of boost! Dane plans to attend Cadillac 2023. Stay tuned for yet another nine second, Tapout tuned ATS-V!
