Had EFILIVE from DansDiesel back in 2014, installed a new turbo and built trans and had another CSP5 tune sent. Made sure my autocal was updated and did the BBX update as well. I get a 0526 error. Tuner tried to help me out and no luck. Does anybody have any suggestions? Error code says to make sure firmware is updated which I have, only option I can think of is that tune file was not created/saved using latest software.
