Well I know the 6.4 guys have a thread like this but I've never seen one for us 7.3 guys, so I figured I would start one.

So like the title says what did you do to you 7.3 today? Maintenance, performance, washed the windows, whatever.


I tested the coolant and found that it was in need of a DCA additive in the coolant. So I went to the truck stop and got a pint of DCA and a 5" band clamp. Put about half the pint in the resivor and I'll see if its any better tomorow. As far as the band clamp goes, I finally got around to fixing my tip that was held on with 3 tack welds and got a good clean clamp on it.

So what did yall do?

my XXL size hands are too big to reach the bolt to unconnect the PCM,
so a friend down in Muskogee, OkieLand "Wes444" who's hands are half the size of mine, installed my Hydra Tuner....

Oh boy, love that Fuel Sipper mode.....
Makes the 7.3L quiet, and throttle response and transmission shifts made me feel like I was driving my '01 Suburban....

What a joy that is.

Drove the truck 90+ miles for no reason lol....

Spent a week hanging close up in a spare room with a fan to dry while I fixed the older dryer twice. Now have a new set and crossing fingers. It dries in less than half the time. I had to triple check at first.

Drove the truck 90+ miles for no reason. First store didn't have what we hoped for in stock no biggy. They said the store in the next town had 5. I didn't call (my mistake). Apparently they dont carry any in stock because they dont want the liability of storage damage its all by contractors now ugh.... So hung dry clothes' in spare room for 4 days more and new set delivered lol.

Nothing like trying to air dry clothes when its 4 degrees outside so your spare room looks like a backyard from the 50s.

Installed the hydra I got from @CoreyCNCFAB ; with the Jelibuilt tunes. Couldn’t be happier truck is running really well. Big difference from the canned super chips thing that was on the truck when I bought it. Install was easy and CNC fab preloaded the tunes so I didn’t have to download.

Would recommend!!

Put a couple new batteries in it. Starter still went click. Tapped it with a hammer and it's starting. Had to haul the dump trailer to the sawmill for a big load of sawdust

Finished up the Cable routing for the Rear View camera,
put some wire Loom over it in the engine compartment, it has to route up too close to the manifold to make me happy :(

the only other choice, was to drill a hole in the floor board and bring it up that way.

got her cleaned up and she is ready to prowl the highways
