tire pressure

Got the tire pressure monitor on my k13gt and have a question for those familiar with it.
The computer reads about 2 psi less than the manual tire guage. If I read the manual right it says that I need to pay attention to the computer and not the tire guage. If I do this the tires will be overinflated per the usual manufacturer methods of checking pressure.
Is this correct?
thanks in advance for any advice.

Yep, we've found the computer reads 2-3 psi lower than a trusted manual gauge. You can either run the correct pressure and just know to add 2 psi to what the computer says, or run them a little harder and don't worry about it.

Honestly, very few riders can tell the difference from a 2 psi change on a street bike. Tires will heat up and change their pressure more than that anyway just from normal riding.

My biggest use for the TPM is to make sure that the pressure stay consistent over time, and doesn't drop noticeably over a few weeks or more. Also, I've had it alarm at me twice now, alerting me to a major puncture in enough time to get off the road and into a safe parking place before the tire went totally flat. That in itself is worth much more than worry about a 2 psi difference.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Ken . I wasn't sweating the 2 psi but do want to make sure the tires perform as expected.
thanks for the response.
