Just a note: I bought a new (in box with warranty) OEM DS4 Stanadyne FIP from local fuel injection service shop last spring.
The screws securing the PMD to the FIP were not properly torqued ; the underlying HeatTransferPad wasn't compressed.
{i realize this is irrelevant to most who remote-mount their FSD}
Additionally , i noticed that the nuts securing the output Driver transistors were also not properly torqued, so i loosened and re-snugged them all.
I did not use a calibrated torque screwdriver , but i improved the mounting/conduction situation significantly.
'Beta' , and 'JD' observed that these were common issues with PMDs/FSDs, and that these problems were enough to prevent the FSD/PMD operating as designed.
