"This graph illustrates how the fixes progressively improved rear-wheel power and torque. All values are corrected to the conservative SAE J1349 ""Net"" standard, the same way OE's rate today's cars. As baselined, power fell off past 6,100 rpm, and you can also see how the fuel pressure decreased even as rpm increased. After calibration, with the fuel system, boost controller, 2-Bar MAP sensor, and ECU changes, the fuel pressure stabilized and power increased, but the peak point still remained unchanged. It took a new upper valvetrain to raise and extend the power curve upstairs. Overall, the gains were split nearly 50/50 between the fuel system and calibration mods and the valvetrain fixes."
