Very interesting. I knew that the Bosch is a better pump but that's a pretty big difference! So there is a reason to put up with the extra noise haha.

Correct me if I'm wrong but you would only notice a difference between the two on heavily modified / high flow applications, right? Ie: it doesn't matter how much more than 100lph they flow if your injectors only spray 100lph? The key is to prevent fuel pressure drops and not overload your fuel pump to the point of failure?
