Okay so i got my auto cal. Dustin pre loaded it with my vin #. The instructions sent say i have to load it to the computer first. I have a mac, so that wont work. I was told all I have to do is plug it into the truck and load it. So which is it? On a separate note... I'm installing the EGT probe, DPF, EGR blocker, DSP 5 switch and PCV reroute. Does it matter what I start 1st? Thanks all for helping a rookie!
