BKP Juggernaut - Strange Chart Help

[gpdb]

I just received a Bare Knuckle Juggernaut Bridge pickup to do testing on, and I'm getting some really strange results. This pickup is already strange as it has a large Alnico 5 magnet in the center (similar to a Super Distortion's magnet), but also has Ceramic magnet spacers on both sides. I can't tell if this chart is accurate because of the weird construction, or if I'm doing something wrong. 

In the chart below, the black line is a Dimarzio PAF 59 and the blue line is the Juggernaut. Both pickups were measured back to back without changing anything other than the pickups connected to Ken Willmott's integrator. No load is being used for either. I also tested the Juggernaut with my LCR meter and all readings are accurate to spec, and I confirmed which wires needed to be linked properly. Any ideas would be appreciated!

Update: I put the frequency generator on each side and measured, and one side looks more normal, but the other side has a weird drop off.

The first one looks like the integrator bypass switch was accidentally selected, disabling the integrator. Just a guess. The second one, I would need more details. The images you posted don't show any electrical connections. What wires are provided from the pickup? Which ones did you connect to? Can I see a photo of the test setup? Sometimes loop gain problems can distort the plot - from clipping due to overload, or excess noise due to insufficient drive from the test coil. Please watch the o-scope display during the test and look for signs of trouble there. It's visible during the plotting process.
