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!

A couple months ago we posted the first ever CT4-V Blackwing dyno chart above 700 whp. Today we reached a high mark running the Brown Belt Performance Package on our flagship car. This time we tuned the car using the soon to be released Tapout Tuning Module (TTM). These modules are more sophisticated than any other devices on the market, giving us the ability for much more precise tuning. You may notice that the new dyno chart looks similar to the 710 whp dyno chart we posted two months ago. However, we now have 85 foot-pounds more torque at 4,000 rpm, and much smoother boost and power curves.

Our good friend John from Michigan is planning to attend the Cadillac Attack event in Florida later this month. We’ve known John for a long time, and second place isn’t really his thing. When he dropped off his beautiful Crystal White Frost sedan we knew he’d want the full Brown Belt treatment. John now has one of the best powerbands ever produced by any ATS-V, and we can’t wait to see what the car can do at Cadillac Attack!
