A couple months ago we posted the first ever CT4-V Blackwing dyno chart above 700 whp. Today we reached a high mark running the Brown Belt Performance Package on our flagship car. This time we tuned the car using the soon to be released Tapout Tuning Module (TTM). These modules are more sophisticated than any other devices on the market, giving us the ability for much more precise tuning. You may notice that the new dyno chart looks similar to the 710 whp dyno chart we posted two months ago. However, we now have 85 foot-pounds more torque at 4,000 rpm, and much smoother boost and power curves.
