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!
