Default Ltrims Min and Max

Is it feasible to get things so dialed in that the min and max you ever see is min -3 max 0

My Average is there at -1.5 ish but min and max I typically see as low as -12% and as high as +12%

The majority of the time the car is + or - 3% but I do see big swings either way on occassion.

Normal? or still too far off tuning wise?

That's a very wide spread. You might look at it by fuel trim cell & rpm & TPS. Maybe the swing is caused on lift throttle coming off of boost?
My idle tends to be off, but it is partly due to 30lb SVOs and stock injector offset.
