I'm going to answer my own question. I got one in yesterday and got it installed. The rev limiter works great and it seems the engine starts easier on a cold start. I also like having a engine bay tach for tuning purposes. I cannot comment on horsepower gains as I really don't know yet but the aforementioned features are enough for me to be happy with it. No issues at all so far and I'm going to recommend the Rev N Nator.
