Excessive Hall Effect sensor noise

I’m having issues with noise on my Hall effect sensors. I’ve tried disconnecting the alternator, running grounds directly to the battery ensuring clearance between the plug wires and sensor wiring. I have photos but I have to change format to upload them. Does anyone have any thoughts on a path forward?

I have been in contact with

I have been in contact with AEM support via Email. They suggested a few things...

1. I have an MSD 85551- I had the Sensor ground and Sensor wire connected to the pickup. This is incorrect. The MSD can output a high voltage and potentiallly ruin the AQ-1. I corrected this by using a hall effect sensor on the crank trigger. Its still a little noisey but far better than before. 

2. My driveshaft speed sensor has a lot of noise as seen in the previous post. AEM suggested that I connect the sensor using a shielded wire. I'll be trying this out today and will report my findings.
