yep because you map in 2-3-4th gear the TRE puts it in 5th gear so you run rich.
and the tuner need to know you have a TRE
If not you will run too lean in 5th and 6th
 
you map rich in gears 1-4 so it will be correct in 5th still will be lean in 6th.
or you map rich in 5th so it will be correct in 6th
