Looking at it from the car world:
The Dodge Demon was advertised as having 840HP and 770 Foot Pounds of torque. *
The * fine print being, you had to use stupid expensive 100+ octane fuel, swap out the air filter for a high flow one, swap out the ECM and change a dash panel.
So did Dodge lie?
I would like to think (I know I would be wrong but let me be happy in my own head) that people in the car world looking at it knew this. Same way I would like to think that people buying a miner know the true speed.
Is it scummy, yes. But it's been going on everywhere for years.
I would not do it and I would like to think the people I deal with would not do it, but it's still in spec.
Same question a bit different. I had a L3+ I put together out of the best boards from several L3+ units. Was over 10% faster then spec. Would selling it as a 550 instead of a 504 be a lie?
As I said in the 1st line it's a tough call.
