Tuning issues...L Trim and S Trim.
Ok, so working on my tune I was datalogging in datamaster. I was watching my L and S trims while I was idling....my Drivers side L Trim sits at +1.6 steady...my Pass side L Trim is almost always sitting at +18. Can someone PLEASE translate for me and tell me what the cause could be?

+18 means that your passenger side has an air leak before the o2s, so the o2s are seeing more oxygen and commanding the computer to put more fuel in to compensate.

I would also try switching the o2's to see if the other side is doing the same thing.
Maybe the other side o2 is going bad and not reading the same 18% maybe a tuning
