About 3 months ago I bought a totally stock 2000 7.3 4x4 crew with 148k and am still learning about these diesels. It runs OK now that I cleaned out the Exhaust Backpressure Tube & Sensor. I have ordered a Donaldson Severe Duty Filter kit for it and am going to do the zoodad mod.
My questions are:
1. How do I know if the stock programming in the truck's computer needs or has been updated, or even if the factory has ever put out updated programming?
2. If the stock programming needs updated, can only the dealer do it?
3. If I end up going with something like a Superchips programmer, does this write over all the stock programming or just parts of it? (If it writes over everything, then the factory program updates would not matter.)
Thanks a bunch.
