2023 CT4-V Blackwing 591 WHP

Matt came in with his 2023 CT4-V Blackwing to have our wildly popular Purple Belt Performance Package installed.  He ended up making 591 peak whp with E53 fuel in the tank, and should be well into the 600 whp range when he increases his alcohol content to somewhere in the E60 to E70 range.  That’s the sweet spot for these cars.  Below E60 we need to pull back boost and/or ignition timing.  And above E70 we can run into fuel system capacity issues.

Very Thankful, Great Experience!

I bought an ATS-V from Florida thinking it was stock. To my surprise the car had a Purple Belt package.  I reached out to Scott and since the very first email he was extremely helpful with questions and information about the package.  Not only he helped me recovered the stock file, he also made sure my Purple Belt tune was revised and adjusted.  The car runs strong and I love it.  When modifying a car having the Tapout team is amazing.  Jorge answered all my dumb questions and I thank him for that.  LOL.  I am thankful for the great tuning experience.

Great Shop!

I took my 2022 CT4-V Blackwing to have the Blue Belt package installed. I live in southern Wisconsin and took the 7.5 hour road trip. They made it worth the drive. The owner Scott was friendly and easy to get in touch with. Jorge, the technician who installed the upgrades, was respectful and clearly enjoys working on the cars. Both Scott and Jorge were very knowledgeable and have been working on Cadillacs for a long time. The garage is clean and well maintained. Professional shop. I would recommend Tapout Tuning if you’re thinking about getting any upgrades to your Blackwing!
