I want to hear that Big Gun in person! Sounds good though even through a computer.
I don't notice the power difference at all from a standstill. The X4 is just as quick feeling of the line and pulls just as hard. Where I notice it is at cruising speed when you hit the gas. The 1000 would take off no matter what speed you were in but not the X4. The closer you get to the top end the less guts it has and it begins to feel really sluggish but like you said, I'm hoping some clutch work will solve that.
