FTP resistance

Hi, I am trying to do a FTP test but am not able to hit the required wattage as the resistance doesn’t seem to be correct. For example, it is asking me to pedal at 160w for 3 minutes but even when I am in the big ring in top gear, spinning as fast as I can, it still isn’t hitting the target, any ideas?

Could you tell us what trainer are you using?
