Finally deleted my exhaust and put on a 4" straight pipe and installed an EGR blocker plate yesterday. Went to load the DSP5 tune I got from ATP/Idaho Rob and it popped up a $0502 error. I was able to fix that problem by updating the config and bbx files needed for my truck as the Autocal I purchased was previously used for a Cummins. After fixing that issue I tried to load the tune again and it gave me a $0536 error code. After more research I found that the tune they emailed me isn't setup for remote use I believe and I checked the vin and license in the tune file to see if they matched any of the licenses on my Autocal but non of them match. I'm at a loss and would like to test my truck out today. I cant get ahold of ATP as they are closed. Anyone have a solution or know how to get ahold of them afterhours. Maybe I'm doing something wrong IDK. Any help is greatful, Thx
