My only experience with RF was when I swapped to the electronic dash. I was able to get it to get rid of the noise with resistor caps but thought in the long run, they would be loading my old iggy just that much more. As a beta tester, I tried Jim's inductive pickup and it worked fine without the resistor caps. I'm not sure if he ever went ahead with production but here is his website if you are interested.

With that said, I wouldn't hesitate to use the resistor caps for just dyno purposes. Not that its accurate but I didn't feel any difference with them on the ole butt dyno anyway...
