It's been a full year since the mod, so no question there. But the tuner said the car was running extremely rich

I can't think of anything I've worked on directly or indirectly that would be causing that.

Were you getting carbon deposits on ur rear bumper at all?

Perhaps dirty maf sensor? Intake filter oil on the plate?

/\This. Within a couple of days of driving the ECU will compensate.
