Not sure what exactly you remapped (spark, cams, F/A?) but you might have blown something inside the engine or fried your cats. A lot the times the sacrifice in torque is intended to protect components or keep emissions within check. If you didn't clear out diagnostic code when you were 'remapping', is the SES light on? Any codes?
