surging.efisurging2.efiI'll start off by saying I am still trying to get hold of all the basics of this diesel tuning. But the only stupid questions is the ones not asked. I have a 2009 6.7 I'm playing with. After flashing it with a mild tune it is surging at wot in 4th gear up. I can see the pilot and main injection duration jumping so I am assuming it lies with the timing. I have attached a couple data logs if someone wouldn't mind looking at them and fill me in to what is really going on. Thanks
