Has any CGT owners experienced this?  Basically when I drive on an uphill incline and shift from say 3rd to 4th at full throttle, it will feel as if though the engine is surging, almost if the car has gone into neutral.  Has anyone experienced this.  THis only occurs on an incline, and not when the the road is flat or going downhill.  It seems the same before and after the clutch change.  Is this normal?  Thanks.
