That ending line is your saving grace. I can tell you without a doubt, cross my heart and hope to die, that my intake mods has made my car a beats. It has not lost any torque or a narrow in power band. My car is flat out hauling through the whole RPM range. I don't need a dyno to tell me the car has gain a substantial performance gain. It flat gets with it. Do it right and you will be rewarded.
