I get a significant power and torque boost at that point.
That's interesting. I don't get a sensation of extra boost through the RPM band. I get a steady very strong pull across the RPM band. Feels like I'm driving a small block V8, put the throttle down and I get a steady relentless pull to the next gear. After I got done with the intake mods and took it out for the first time, I knew it had added a lot of power.
