what manual is telling you this? if i recall, the FAQ says 128psi is the minimum, and they should all be 28 psi within each other. didn't specify a maximum

"When the compression is found to be too high in one or more cylinders, this would be an indication of excessive carbon buildup in the engine. It can only be corrected by performing a chemical de-carbonizing process on the engine or by removing the cylinder head(s) and physically removing the carbon that is attached to the cylinder portion of the head(s) and the tops of the pistons."
