While it wasn’t a particularly hot day, Big Bear’s density altitude was reported as 8,200 feet, resulting in a higher true airspeed compared to indicated airspeed. The pilot continued the turn to final but overshot the extended runway centerline. There were other factors combining to cause the overshoot.

Fuel mixture management changes for the better, because the manifold pressure remains constant for takeoff and climb (full rich) regardless of altitude and density altitude below the critical 18,000 feet. Moreover, the engine mod moves the airplane’s CG forward so you can load more stuff in the cabin.
