Ken brought his new 2023 CT4-V Blackwing to us for the Blue Belt Performance Package. We dyno tuned using the new Tapout Tuning Module, and set him up with various calibrations ranging from 471 to 528 whp, all on 93-octane pump gas.

Shawn shipped his completely stock 2017 ATS-V all the way from the west coast for Jorge’s magic touch. We installed our full Purple Belt Performance Package ensemble, including EPA catted downpipes. This M6 car made 473 whp on California 91-octane fuel and 602 whp on E57!

We just completed a Blue Belt Performance Package installation and custom dyno tuning for Nathan’s ultra clean M6 CT4-V Blackwing. Using our soon to be released Tapout Tuning module, we produce a much smoother powerband than any other tuning device for these cars. We also properly compensated for the carbon fiber intake lid, circumventing DTCs P0171, P0174 and P1400. We create seven different calibration maps that are stored and can be switched on the fly in just a few seconds using the free cell phone app. Here were the final results on 93-octane pump gas:

• P1 = 478 whp
• P2 = 498 whp
• P3 = 509 whp
• P4 through P7 = 513 whp

It’s safe to say Nathan drove a completely different car home than he arrived with!

We just completed a Purple Belt Performance Package installation and custom dyno tuning for Charley from Florida. Using our soon to be released Tapout Tuning module, we produce a much smoother powerband than any other tuning device for these cars. We also compensate properly for the carbon fiber intake lid, circumventing DTC P0171, P0174 and P1400. Seven different calibration maps are stored, allowing Charley to choose from 475 to 598 whp in just a few seconds using the no charge cell phone app.

P1 = 475 whp (93-octane)
P2 = 491 whp (93-octane)
P3 = 515 whp (93-octane)
P4 = 571 whp (93-octane, plus methanol injection)
P5 = 585 whp (93-octane, plus methanol injection)
P6 = 598 whp (93-octane, plus methanol injection)
P7 = 598 whp (93-octane, plus methanol injection)

Fabian pulled into Exodus Performance with his bone stock 2017 ATS-V. We remoted in and turned up the boost, producing peak power of 488 whp. He has some mods planned for the future, so stay tuned.
