First time I have seen this and it happens to be on my own personal vehicle. I always have to do a full flash. Sometimes all the values don't get transferred with just a cal flash. Example. I put the idle timing at -15 just to prove my theory. Truck white smokes like a train while idling. Then I change my timing tables back to normal. Do a cal flash. Truck smokes like crazy. Read the tune. Says correct numbers. Do a full flash and it's fine. I've tested this number out times making real obvious changes. Changing defuel to 10mm. Adding a lope tune. Different things like this. Only a full flash guarantees I get all my changes flashed. Why is this. It's so annoying. Never had this happen before.
