Jeff was here last summer to have us install our carbon fiber package and a set of Tapout Tuning downpipes. That carbon fiber package included the airbox lid with oversized MAF tubes, so he picked up some nice power gains but was ready for more.
He decided to jump up to the Purple Belt Performance Package plus Mace Stage 1 camshafts, valve springs and retainers. After completing a custom dyno tune, Jeff’s M6 CT4-V Blackwing put down 605 WHP, which is nearly 200 WHP over stock. The cams and springs don’t serve to increase peak power. Rather, they extend the top end of the powerband. This makes the car faster and more fun to drive!
This Blackwing now looks the part, and has the power to back it up.
