I honestly don't think a tune would be worth much (5whp?) if all was being done was correcting your A/F here.
Does the car surge or feel less smooth than before the mods?

Lean condition is a possible worry. I threw a lean code shortly after installing my intakes. Thats why i opted for a dyno pull to see if things were checking out. I would say 5hp is a good guess on gains from a tune with bolt on's. It has been to long for me to comment on smoothness of power delivery pre and post mods.
