-Your A/F corrections(short term or immediate fuel corrections) are affected by the "tip in" table. This may need to be adjusted to better work with your injectors. This would explain the difference in your A/F corrections(short term trims) and your A/F learning(long term trims).

Based on what you explained, there seems to be something more like a mechanical issue causing these problems. A wideband will help here.
Yea. I am thinking it seems mechanical. The tune was spot on. I actually watched when the fueling went to crap. Something is leaking, malfunctioning or gave out.
