Is he the only one winning? Nope. I’m saying you can’t move torque down, or even build torque below useable RPM and not give up horsepower where it counts. That’s simple science.
What you are asking me to believe (because this guy didn’t say it, you are) is that he is making more torque below peak torque and gaining horsepower in the upper rpm range. If so, he must be a god because he’d be the only one making the claim.
