It's not lugging, it stumbles as if it's starving for fuel. The car weighs about 2000lbs and will break em loose any gear at almost any speed, even in 5th at 90mph.

Takes off from dead stop with no problems, only stumbles when taking a corner at low speeds from idle, let the clutch out accelerate stumbles then clears up.

I can take off from stand still in all 5 gears no stumble.
