Mark,
My interpretation of the tune as is:
- Taz set you up so that it will still unlock at WOT. Try setting D1008 to 100% for all cells.
- D1002 & D1005 are controlling converter lock - D1002 won't lock it until 76MPH @ 100% throttle, D1005 is requesting an unlock if you go 100% TPS while slower than 70MPH
