Exactly what I said. HPT says its not locked so why cant i even read with EFI then? It is locked somehow.

Even if its not locked, EFILive can not read a HPT custom OS, as it's built difrent then a stock tune file. EFILive should be able to read a HPT modified stock tune though, just not COS SD 1 bar, 2-3 bar type of tunes.

So how would I go about reflashing with EFI?
From what Ive heard about this problem, you have a couple options:
1. use the HPT cable to reflash a stock OS (really doesnt matter which one, you can just do a full flash with EFILive with the correct one later anyway)
2. Ask HPT for the seed key so EFILive's bootloader can get access to the ECM/PCM and flash it
3. Buy a new ECM/PCM

Bill at HPTuners tole me I need to do a reflash with a stock tune with HPT and everything should be fine.
I have done that and still no dice. I appreciate his help and feel bad if I stepped on anyones toes but that is water under the bridge.
Quite the can or worms I have opened up. All I want is a car that runs. Counting my deployement, modding the car and now trying to tune it, I have not really driven it in almost 9 months. Sucks to be me.
Jason at LS1tech is willing to flash the pcm for me if I send it in. That might be my best option.
