Dave just purchased a beautiful new Argent Silver 2023 CT4-V Blackwing M6.  He flew from the west coast to New York to pick up the car, then drove it to our shop in Ohio for the proper break-in mileage.  We upgraded him to our very popular Blue Belt Performance Package, and changed the engine oil and filter too.  His powerband looks fantastic like usual, making 527 peak whp on 93-octane.  We also set Dave up with 91 and 100-octane tunes, which he can switch to within a couple minutes using HP Tuners.

Kyle and McKenna dropped off their completely stock ATS-V.  Two days later they picked it up with another 100 whp.  And just like that, another Blue Belt Performance Package is on the road delivering maximum smiles per gallon!

Jonathan from Texas was one of our first CT4-V Blackwing Blue Belts last year.  A few months later he upgraded to Purple.  And now he’s taken another step up to Brown Belt.  His current powerband peaks at 716 whp and 719 wtq, giving him one of the most powerful Blackwings on the planet!

Now that HP Tuners has granted us access to tune the E99 Global B ECMs, we’re finally able to tune these cars to the nth degree. Check out our latest 747 whp dyno chart, running Brown Belt Performance Package on E65 fuel plus methanol injection. New parts recently added include the ATI Super Damper, Xtreme-DI fuel injectors and some high performance ignition coils (coming soon).

Testing and development continues on our ATS-V Black Belt Performance Package. We started out by setting the new world records of 836 whp and 8.77 seconds in the quarter mile at Cadillac Attack in January 2023. In the last six months we’ve made 40 dyno pulls above 800 whp and today we have new we have a new record of 1,009 whp! Check out how peak power continues to climb, all the way past 7,000 rpm!
