Not sure what your point is. It’s a TOOL. If used correctly, you WILL make more power.
The dyno gets blamed for virtually everything under the sun, but a junk car, piss poor tuning, junk chassis, **** converters...none of that ever happens. Just that the dyno is worthless and junk because we don’t “race” them.
We don’t race torque wrenches either, but they are a tool.
