Are you in a huge hurry for any reason? Can you do better on the MCAT? If possible I would retake if you feel you could do better with a gap year and dedicated prep time. Don't wind up a reapplicant, your GPA won't always make up for a low MCAT. Better to apply once and do it 100%.
That said, I know Texas has its own thing going - hopefully someone who knows Texas schools better can weigh in.
