As a test I raced a friends Evo with the flappy hooked up and with it held open, multiple times each way.
With flappy I come around him at the top of second gear and hold a little over two car lead at 120mph.
With it held open he holds me off by a fender at 120, enough real world info for me to leave it hooked up.

Thanks for that post. I"ve not messed with enough of these to know one way or the other.
