AMR rev box

Has anyone used one of these on their Wolvy? If so how did it work?

I tried it a few month ago I it was worse than the original. I didn´t noticed any significant power improvement and I couldn´t start the engine in Forward or reverse even with the brake pressed. My top speed with the AMR cdi was 53 MPH and with the original it reached 57 MPH (in the dash meter with rear wheels up).
So after that I came back to the stock CDI and got back the ability to start in gear and a couple of MPHs of top speed.

Thanks for your post, I was woundering if these did much more than stock.
