When I originally had the remap on my HDi I was having hesitation issues (also when cruising at constant speed). It turned out to be a perished seal that had found its way into the high pressure fuel pump, causing loss of fuel pressure in the common rail.
Eventually got to the point where it would go into limp home mode in hard accel as the ECU was detecting low fuel pressure.
Was sorted by having a garage strip and clean the high pressure pump.
