Joe, They advertise that it pulls the torque down from the top, not from the bottom. Right now, at about 4500 RPM my engine begins to pull like a horse, but that's fairly high. If the cam indeed pulls the torque down from the top I'd consider installing it, but if it pulls it from the bottom I wouldn't want it. I'm looking for more low end torque, which seems to me would be more usable.
