Aztec F, RPM difference when synced

[lenvining3]

All of you Aztec, or twin drivers for that matter, my RPM gauge seems to be off. When I sync the props (by sound in my case) the needles don't match up. The RT engine is always indicating higher than the LT engine and usually about a difference of 20 or 30. Like 2400/2430 or 2200/2230. Anyone else have this issue with the needles not overlapping closely?
