Last year Kaylee and Jonathan drove more than 1,000 miles from Texas for our Blue Belt Performance Package. This week they upgraded to Purple Belt using the soon to be released Tapout Tuning module. This unit produces a much smoother powerband than any other tuning device for these cars. And it stores seven different calibration maps, that can be switched on the fly in just a few seconds using the no charge cell phone app. Here were the final results:
• OEM baseline = 426 whp on 93-octane
• P1 = 445 whp on 93-octane
• P2 = 500 whp on 93-octane
• P3 = 510 whp on 93-octane
• P4 = 520 whp on 93-octane
• P5 = 584 whp on 93-octane with methanol injection
• P6 = 599 whp on 93-octane with methanol injection
• P7 = 619 whp on 93-octane with methanol injection (see attached dyno chart)
Kaylee and Jonathan now have the most powerful CT4-V Blackwing in the world, except for our flagship car.
