Jittery Timing

I have recently built and fitted a Megajolt using a MAP sensor.
When the timing marks are viewed, at idle, using a timing light and running EDIS only (no Megajolt connected) the timing is rock steady at 10degBTDC. With the Megajolt connected the timing mark tends to be jittery i.e. not steady any more. The ignition advances OK when the engine is revved, so the Megajolt seems to be working OK. The car also drives OK.

Do I have a problem or is this normal?
