So, any potential problems driving deleted with an '07.5, 6.7 on the stock tune?
I'm stuck in an odd situation... Have had a nightmare of ECM problems, finally got a remanufactured ECM in the truck that seems to be behaving but I was told NOT to clear any codes relating to the security SKIM key until the ECM "learns" the key and the code is cleared from a number of cycles. I've already driven the truck about 20 miles and gone through a number of start cycles and it's not clearing so I can't flash the ECM with a tuner since that deletes all the codes. It seems to be running OK, sometimes rough on first start but then settles out after a few seconds. Anyway, should I be worried driving it more with the stock tune? Thanks.
