You have made quite a bit of progress. You went from 2.85 time the limit to 1.03 time the limit an improvement of 116%. or more then halfing your CO output. I don't think the DUI will get you ther but if it does then Grate. If not then the last thing I would try is a Catalitic converter. You could have a muffler shop install it with flanges and remove it after the test and replace with a straight pipe.
