LTFT's Will not Display or Datalog using Performance Tune

[davedyno]

Hey guy's, I need a little help. I have a U7146 with v.7r50d serial 20009fa CALID RVAFAT6
01 Mustang Gt Auto Vert
Dragon Plenum
Dragon 75 MM TB
Tunable CAI
3.73 Gears
Flowmaster Catback
FAST Wideband A/F meter

Question, Predator will not datalog or display LONG TERM FUEL TRIMS using Performance Tune, yes Pedator say's I'm in closed loop and EGR is on and working, the Short Term Fuel Trims will display and Datalog OK .
Now when I remove Performance tune and re-installed Factory Original tune Predator will display and Datalog LTFT's OK. The problem is only when using the Performance tune. Motor is running in closed loop warmed up.
Car runs fine with no drivability or other problems, gas mileage is also good.
Thanks
Dave
