Steve’s 2023 CT5-V Blackwing came with a manual transmission and 668 horsepower from the factory—but that just wasn’t enough. So we cranked things up with a Whipple supercharger, our PD3 cam package, fuel system upgrades, and a Corsa exhaust. Now he’s slamming gears with a monstrous 945 WHP! This Blackwing flies. We’d also like to give special thanks to our friends at Exodus Performance for the tuning tips.

John from Ohio wasn’t happy with a competitor’s tune, so he brought his car to Tapout Tuning for the expert treatment. We topped off several low vital fluids, secured a loose intake hose clamp, and delivered an impressive powerband on our in-house Dynojet. Now that’s the Tapout difference.

Len rolled in from Pennsylvania with his Blue Belt mods already installed, ready to take things to the next level!  After knocking out a few gremlins, including a leaky charge pipe hose, some tricky vacuum line routing, and a couple of pesky exhaust leaks, we strapped it down for a custom dyno tune.  The result?  A clean 497 whp through catted downpipes!  This build is smooth, strong, and seriously impressive.

James brought in his stunning 2024 CT4-V Blackwing Arrival edition for our increasingly popular Purple Belt Performance Package.  Now he’s headed back to Texas with an extra 200 horsepower under the hood.

We have remote tuned Cadillac V cars in 24 different countries so far.  However, we don’t often have the opportunity to tune cars in the country of Oman.  Mohammed has a 2017 ATS-V with our Blue Belt Performance Package and we set him up with custom tunes for both of his common fuels.  95 RON is similar to 91-octane pump gas in North America and 98 RON is close to our 93-octane.
