So as follow up, to update the string.
It has been four months with the FBO box on my Charger. I am enthusiastically thumbs up on the result. The car is running really well…plugs not fouled, starting easier, smoother idle. I have had the car out a bunch of times for cruises and shows and things have been smooth.
I do not think I will put one on my bone stock 440 Challenger which runs very well on just a standard Mopar ECU. But the Charger motor having the bigger cam, etc. had seemed to really need help and the FBO box was a very large improvement over an original Chrome box that I tried and the HiRev box from JEGS that I also looked at (and is successfully on my Challenger now).

P.J. O'Rouke: "The old car ran perfectly, right up until it didn't."
