-swap sensors
-swap sensor wires around. I know vems can be picky about this
-adjust sensor depth
-make sure the sensor wires are well shielded

If the sensor is aftermarket it could be giving you issues, I've tried one of those and the spikes were lower than oem on the scope, so pretty useless.
Like everybody else said, try getting them closer, pretty sure that's the problem.
Could also be some chipped tooth on your ringear.
I've had issues with hall signal window being too much at the edge, I'd get some random missed triggers due to belt slop. Doesn't seem to be your case but worth a look.
Another idea, unplug the alternator for a quick test, could be a noise source too.
Unlikely but have you talked to Marc about the reversed pins on sensor, just in case?

I used to have severe issues with it at times and ultimately didn't get them fixed until I purchased a harness from EFI express along with switching out of the NGK to Bosch plugs. Before, I ran the NGKs with a modified URS4 engine harness to VEMS Econoseal.
