Dyno com dynos just read really low, they aren’t like a dyno jet at all.

great for tuning under load etc… throw the numbers away or try again on a dyno jet if you care about higher readings
Matter of fact, dyno com software used to have a way to scale it to dyno jet numbers, the multiplier shifts to 1.14 or something like that.

Also Dynocom makes a bunch of different dynos, hub and drum. The internet always seems to talk shit about how high Cleetus's hub Dynocom reads

I have no clue. I asked chatgpt and it said they should have the 486hp like in North America. But this prasitic drivetrain loss is well known with American cars unfortunately.
To be honest I have always been kind of sour on the Mustangs dyno numbers. My 2020 Mustang GT made 422rwhp stock and with the Ford Performance Power kit it made right at 444rwhp all SAE but it was a dynojet. However, that is only a 10% drivetrain loss.

Im on the other end of the spectrum now, I have a car that makes way more than advertised horsepower. My G87 M2 is rated at 453hp and I made 458rwhp SAE. BMW with their latest M engines are way underrating them.

I had many German cars and they were spot on. They advertised crank hp and you get whp
