Is it only possible to READ from a stock chip with moates Burn2 and tunerproRT?

I think have the chip start and end addresses and the buffer start and end addresses correctly set up as per eagle marks post here Reading Stock GM Chips Burn 1, Burn 2, AutoProm TunerPro Flash and Burn (gearhead-efi.com)

I just switched laptops and im trying to read my last tune off of a SST27SF512 that was in the truck running and driving and now when i try to read the chip with the Burn2 and tunerproRT all the values in the tables show zero and its clearly not a good read.

I downloaded another $0D bin off the website here and i can open it and everything looks fine so its not an opening issue.

Is the process to READ from a 27SF512 the same as it is to read from a stock chip? I currently have the addresses set up for as if i were going to WR​ITE to the 27SF512 chip
