Fuel pressure too high

Excessive fuel pressure can over power the Carb Float Valves causing the float bowls to overfill resulting in an excessively rich fuel mixture.
Does your fuel system have the, Now Required, Fuel Return Line with the Restricting Orifice installed?

Yes I have to restricted orifice.  I think I will just watch this situation since it only happened today during throttle reduction and then was normal after landing.  I was more worried about whether too much pressure could cause power loss.  Otherwise engine runs great.  Ken

From the Installation Manual:

Fuel pressure in excess of stated limit can lead to an override of the float valve with subsequent engine stop.

6.1 psi is under the 7.2 max. Sounds like you need to reset the high psi alert number on your Dynon. The average person seems to run between 3.5 psi - 5.8 psi. Some of these variances with people's individual plane is caused by a poor reading sender, poor ground connection, brand of mechanical fuel pump, do you have an electric one and is it on, or the recirculation hose orifice size, if you even have a recirculation line, vapor lock occurrence, ect... So some variation can happen.
