Please Help

i know its long but please read im desperate!!
Ok guys so my car is at the shop with the new FP red installed an a whole bunch of goodies but my tuner here from JMS tried to access the ecu via a tactrix 2.0 cable to tune my car but no luck my ecu is locked. . So my tuner thought my car might have been flashed by ecutek by the previous owner (because i bought the car used) and locked so my tuners first suggestion was to send my car to the dealer and try to get a base map flash but no luck the dealer could not get into the ecu saying it was locked. My seccond option was to send it to vivid racing because they are an ecutek dealer and they said they could unlock it. So i sent my ecu last thursday through overnight shipping, the vivid racing tuner worked on it and confirmed my car was tuned before by ecutek but said he did unlock it. I got the ecu back today from vivid and took it to my local tuner here in san antonio and no luck connecting via the tactrix cable it still gives him the message could not connect to source ecu may be intentionally locked. After that my tuner connected another evo x's ecu in my car and he could read it WTF????
Here is the weird thing though:
-I bought this car from a chrysler dealership which they bought off an auction
-I did a carfax report on the car and nothing suspicious or out of the ordinary was in there, one owner.
-Bought the car at 10000 miles and at 14000 miles my turbo dies.
-Carfax stated the car was owned for 7 months by the first owner and then sold (to the dealership where i bought it)
-Car was running great before my turbo died when i was stock and all along i had a ecutek tune.
-Even with a locked ecu my car turns on everything works
Please help i have no idea what to do

any advice is appreciated.
