Now, with that being said, you would be doing yourself and your powertrain combination a huge favor by switching to the 2007 and later PCM because there are so many more tuneable items in the 2007+ PCM's.
One of the first things I would do would be switching to the later PCM. Next, I would install a wideband setup so you can see the AFR and get the fueling in order.
