just from the experiance i've had people have had good gains with them, cant see how it would be worse than stock as a minimum you could put the stock curve on and it would be the same, unless it was not set up properly. I've seen a few of the rd chaps with them on and boy does it change them.
I know the honda is a good one but i bet the system would allow for changes that the std pgm cant cope with, you could also mirror the settings of a HRC pgm for less money!. I imgaine the main reason for him not doing anything is just pure demand
