Okay, having seen the data I guess I have to become the bitter, skowling skeptic.
The runs with the e-ram installed but turned off was 236.2 hp and 235 (only 2 runs). With the e-ram on it was 234.4 to 236.4 hp (5 runs). And there was only one run without the e-ram attached at 234.7 hp.
Now I know even the manufacturer isn't claiming hp gains with the device turned off. But from these results I would more readily conclude the device works better when turned off, but installed. The avarage gain with the device installed but turned off was greater than the average gain with the device on.
So I am forced to conclude the results are statistically not significant. Not enough samples to remove the variation inherent in the test equipment and process. And not enough affect by the e-ram to overcome those limitations.
I'll keep my $300 securely in my pocket.
