Known problem. Performance is bad due to zl10353 demodulator driver and 
also qt1010 needs some changes after demodulator driver fix. But I 
cannot fix it because I don't know what is the meaning of some zl10353 
registers needed to get it working better. I wonder if those are for 
AGC2... Same demodulator driver is used by too many cards, therefore it 
is hard to change without knowing exactly what to do.

This can be fixed :) But unfortunately it does not have nothing to do 
with tuning problem :[
