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.

Sam drove in from Virginia with his beautiful Argent Metallic 2024 CT4-V Blackwing. We added spark plugs and did custom dyno tuning for peak power gains of 82 whp and overall gains exceeding 100 whp in some parts of the powerband!

Sam from Pennsylvania has a killer CT5-V Blackwing build that produces 858 whp with 18 pounds of boost.  The build features our PD3 camshaft kit, Magnuson supercharger and E60 fuel.  The next limitation is the stock fuel injectors on the top end, so we’ll be sticking with factory shift points for now.
