Quite possible, since it's "sister" coaster Wild Thing at Valleyfair! has them. I think the bunny hops on Mamba are more intense than on Wild Thing, but I highly doubt the tunnel has anything to do with that. I like the tunnel, but I really have no preferance.
By the way - Wild Thing glows in the dark when in the tunnel. I thought that was pretty cool.
