Narrative:

Shortly after liftoff from gdx we got a 'tailwind wind shear' warning. Aircraft felt sluggish and seemed like it wanted to settle, then kept on climbing. No other indications of wind shear (airspeed fluctuations, convective activity, gusty winds, etc). Winds were calm on the surface. Engines slightly overboosted, all other indications normal (egt, N1, N2, etc).
