I have my O2 about 8 inches from the end of the collector. In order to get a proper reading at idle I have to put on a 24 inch extension made from flex pipe.
I can't reley on the O2 reading below 4,000 rpms without the extension on. After 4,000 or so it reads fine.
One thing I have noticed though is that the O2 reading is higher (leaner) in first and second gear, than in high at the same rpm's.
I've been tuning off of the high gear readings. And it seems to work.
