You actually lose power with the G3 down low. And a modest gain in the middle to high revs. The G3 will give you a stronger boost up high but... add an exhaust and tune with the hose and filters. I think the overall power delivery will yield more realistic use of power vs low rev power loss and higher rev power boost.
