My registration is due in August and I have to provide proof of the K01 flash. I haven't had to have any dealer touch my truck since new. I am afraid that along with the K01 flash that they will change something else and hurt the way my truck runs or affect the fuel mileage.
How many of you have had it done and did it affect the truck or mileage?
