As a minimum, the YIO-540 contains roller tappets.  Not sure that the XIO necessarily does.

 You purchased the experimental non-certified version of the engine.  The certified costs around $3K more!  In reality it is the identical engine, just a different part number.......  Call Lycoming, I did.

Having discussed the issue with the folks at Precision, the only

difference between their experimental units and certified is the color

of the servo body and the data plate. They are otherwise identical.

 I have YIO-540 too. Fuel servo, flow divider, fuel nozzles and data plate are different but still must meet same test cell specs.
