Ok so i just got efi live and a dsp5 switch off ebay for a steal, just been messing with it a little bit not really changing any thing but, i disable the egr (c2401) and am still getting P0405 and p1404 codes both which have to do with the egr valve. i also set the maximum and the minimum on the egr's parameters that the truck would never see. i was think that was the issue but there still coming up. What am i doing wrong that these codes are still coming on???

When you shut off teh EGR function in the tuning, the diagnostic side of teh ECM will still look for it to work. Just like with a DPF delete, you still have to kill the codes after you shut it off.
