Tele's are like that, they can really vary from piece to piece, it has to do with the break angles of the strings at the nut and bridge imho. Stiffer angle = stiffer action. Overall setup including truss rod relief all come into play and contribute to this. Stiff action isn't always bad if you are looking to use slinkier strings and still not loose too much tension. My bud's Super 400 has a bigsby on it that makes the bridge break angle so shallow that even with the 13's he has on there they feel like loose rubber bands.
