So I finally found a great deal on a 2008 LMM and got my self my first duramax and so far can't be happier! That aside I have a quick question in regards to EFI. The truck currently has EFI with the dsp5 switch but didn't come with the box. Tunes are from duramaxtuner. I want to put tunes on either from Kory or Rob. My question is.... can I send one of them my old autocal that I used on my 5.9 cummins and have them put tunes on that and then send it back to me and I download it to my truck? Hope that makes sense! Thanks guys!
