Your haplogroup seems to be Q-CTS748, common clade in Mexico and El Salvador, https://www.yfull.com/tree/Q-CTS748/ could be of mayan extension, but i am not that sure, i have to read more about it. Very curious, you actually had luck because like i said, is not that common scoring Q in Y-DNA for Mexico, only in countries like Bolivia or Paraguay is a bit common.
