I recently decided to get the BluMax 1350 injectors and got rid of my old 1600s. I recently checked my fuel trims and both the low and mid are both around 6%, so I need to change the global fuel compensation from -50 to -45 or so.

However, yesterday I was noticing that whenever I went full throttle (haven't done this in awhile) it would peg the wideband at 10:1 (probably richer) and misfire/sputter a lot since it was so rich.

These two things are conflicting, I was thinking my fuel trims would be -6%, but the opposite is true. It wants to be richer at idle/cruise, but its so rich it doesn't run right in open loop. Other than injectors I haven't changed anything on the car.

Ideas?
