I can't help but notice the 2690 RPM and 16.3 Gal per hour...
Crazy winds today over the SE.

It is highly unlikely that the pitot tube is causing a loss of 8 knots...
The engine runs well LOP at about 11.0 GPH truing about 185.
I am just getting to testing cruise speed, but it seems the majority of 10's are getting around 165 at 11 GPH, at least in the 8-10K altitudes. 185 seems a bit optimistic. Definitely want to check your TAS indication performance. May have a static issue.
