I just picked up a 03 f250 and when I test drove the truck everything went great bought the truck and it’s been a headache ever since. But on to my dilemma the truck is studded,a Ficm of some sort, and supposedly has a non stock turbo but it doesn’t run the best hates the cold and every now and then idles like trash at stops. I’m hoping it’s the tune that’s in the truck I’d like to get a custom file from someone but my sct hasn’t been updated and I’m worried if I update it I’ll brick the truck it’s already showing a p0403 and p0405 am I ok to update and get a custom tune or will it brick it?
