Dead time

so ive got a 2jz with a haltech elite 750 running Fuel Injector Clinic injectors which does have a data match sheet, so the car has always been tuned without the dead times being added into the ecu . So i decided to add it just to see what it does but for whatever reason i almost have to go to 0 in VE or Injector time to get it to idle and even then it is idling at 9 AFR. I just dont understand why this is like this

if you have used the correct injector data then there most likely will be something else not set correctly in the base set up like fuel pressure base setting in the software just a suggestion but email your map to the tech guys at haltech they will be on to it to see why
