CDI's on a dyno

[cals400ex]

i was wondering if anyone has cdi boxes on a dyno for a 400ex? an individual is trying to tell me if you put a WB box on a dyno you will see a 1-2 horsepower gain. i say that is a load of crap. but i can't prove anything without a dyno. i know i didn't notice anything but an increased rev and my bike not starting. i am interested in seeing other brands too if we can find that. i thought i saw somewhere where the big gun didn't do too bad on the dyno but i don't think the WB has much too it.

2 horses i doubt, but its a different curve and higher rev limit, they only are good if you motor work done , in most cases they don't do anything for you. Also most of the cdi's are remarked 96-04 xr250r cdi boxes. Conviently what they forgot to tell you is that they make the bike hard to start, even worse when cold.
