I hope this is the right place to post this thread. I recently purchased an 05 LLY truck. It has efi live dsp5. I have a loss of power issue, no matter what level I'm in. I use my insight to check the codes, but there are none, but when I clear codes my power is restored for awhile and then reverts back to low power and no codes. I got the EFI live tune file from the origional owner but it won't open in V7, it's just sits there initializing, but I can open it in V8 but of course I can't do any reading or editing. So I thought I would try to read and copy from the PCM but it only downloads 72k with V7, I tried reading the PCM with V8 but after a minute and 11 seconds it gives me error script exited with code $0101: no data recieved. I used high speed, low speed, alt keys, no alt keys, pulled radio and info fuses and the same thing every time, one time it got to 740k but then it froze again. I have no aftermarket accessories in this truck. I am new to EFI live and have been reading and reading forums to help me out, but I am stuck. Also, the tune is suppose to be 200hp, tow tune, 60hp and 80hp, but even after I clear my ghost code, the 200hp does not feel like 200hp. Can some one please help? I'm at a loss. I have attatched my tune to this thread, I hope it works. Any help would be great, thanks.
