It reads about 10 to 12 percent high.  In the EPI 800 the flow measurement also drives the fuel-remaining display and total low fuel warning.  After consuming 35 gallons (fuel truck measurements) the totalizer will show a use of 4 or 5 gallons more.  So, a 7000 ft 185kt leaned cruise showing 8.8 to 9 gph is more like 8 gph.

The EPI 800 fuel tank quantity indications are absolutely accurate however.

Remember that the soft mounts only take away "felt" or perceived roughness, they do nothing to correct the cause (such as making a 4-cyl run as smooth as a 6).

I take it that your timing is ok.

At idle, the Continental IO 360Gs in my Skymaster (6-cyl) doesn't care whether you lean or not, hot or not.  The Lycoming IO 320 at idle requires leaning to stop the "backfires", especially when hot.  I believe the difference is the way the Lycoming and Continental injection systems work.  Scott Krueger
