Got the edge cts2 and Kennedy ecm installed. First start did have change fuel filter on dic and oil life was down to 11per cent. Since both were fresh I reset olm and ff life. No cel, no p0087 but stored codes for def sensors and maf which I've not had previous. Cleared those. Emailed John and he said those were normal for first start. Went for a spirited drive and all was well - truck seems smoother with more pep for sure. Won't be towing for a while but looking forward to it.
