 (31) Do Test No. 6 - MEC Trim (AMM 71-00-00/501).
 NOTE: A VSV Dynamic Rig (AMM 75-31-00/501) should be done after
____ the replacement of high time MEC on a high time engine because of the difference in the MEC fuel schedules. The high time MEC usually has a richer fuel schedule than a new or overhauled MEC. The VSV dynamic rig makes acceleration characteristics better by optimizing the HP compressor efficiency and helping to adjust for a lower nominal fuel-flow schedule.
