I see what you are talking about and I can't explain it either. Like I said earlier...I did not install it for those particular claims, but it definitely works as far as the other claims go. Whether it increases HP or torque and at what RPMs, I will leave to others. But I can attest through experience with this thing, that the voltage & RPM fluctuations are GONE. I'm satisfied with the purchase and you are satisfied that you didn't...so it's all good.
