But again like Lance and many others have said, when dyno-ing they have the hood open with fans blowing at the engine that accounts for the 2 whp gain but on the streets it may not give you the full 2 whp increase.

I think what you're trying to say is that dyno's do not correctly replicate real world conditions.
