Their goal was to obtain 800 crank horsepower, and after factoring in a 25 percent drivetrain loss on the Mustang Dyno, final numbers show 642 awhp and 616 ft lbs of torque. Using Softronic ECU flash technology they were able to pull everything together, and used VP 109 fuel to get these final performance numbers.
