Like @Iftah said, set encoding: null.

Full example (less error handling):

request = require('request');
zlib = require('zlib');

request(url, {encoding: null}, function(err, response, body){
    if(response.headers['content-encoding'] == 'gzip'){
        zlib.gunzip(body, function(err, dezipped) {
            callback(dezipped.toString());
        });
    } else {
        callback(body);
    }
});
