Any suggestions
 

So as some peeps know I have a ported upper and lower mani and bored throttle bodies. I went to have my car tuned yesterday and my tuner said my AFR is all over the place. At wot bank 1 is reading 1.5 to 2.0 richer than bank 2. When he attempts to adjust the fuel and go up both banks go down. At idle they are both the same. Any ideas??
