It runs.
All good for the first 24 hours. Dry as a bone underneath the truck. Had an issue with the first "hot start" the next day, when I turned the key, it immediately threw a MAF and a TPS code and went into engine failsafe mode. I cleared the codes with a Matco MD9001 Quickscan tool. Turned the key again and all was back to normal. Thinking I had some slight MAF cleaner film burning off of the MAF as it was the first time it got heatsoaked after the build. Maybe one of the pros here could speculate on why that happened?
Anyhow, I updated my spreadsheet (in the first post) again for you guys, I hope it helps to have an example of what exactly was replaced at 100K on an E53, (at least, in my instance). It was nice to just be able to CLEAN everything while it was apart. Don't ask me how many rolls of shop towels or bottles of degreaser/brake cleaner I went through. 20+ easily. Thanks stupid old leaking S/C oil drain hose.
I haven't put the truck under heavy load yet. It had half a tank of 5 month old gas, I added a bottle of Techron fuel system cleaner and topped of the tank with fresh 93. After I burn through this tank, I'm going to follow the Dinan "black box" tweaking procedure to verify a certain airflow voltage level, just to be safe. Dinan says upgrading to the Vortech Si-Trim impeller (Much more efficient operation, and 12% more air) doesn't require additional fueling.
Differences between the S-trim and Si-Trim supercharger impeller wheel can be found in this thread:

Initial impressions under light load.... this thing seems to require absolutely NO throttle to get up to the speed of highway traffic. VERY responsive. The effects of fresh plugs/O2's/blower shaft bearing/impeller & etc. is making itself known. The truck WANTS to FLY. I can only imagine, but I have to finish burning through this gas first. I'm thinking this impeller blade might not make a ton more peak power, but it makes a BIT more under the curve.
I might be bench racing, but I'm thinking that as it sits now, it should (slowly) nudge out a X5/6 50i in straight line acceleration. I'll still be a small spot in the rearview of an X5M and X6M though. Someone is always faster.
DynoJet 424xLC numbers to come soon..........
but for now.... happy pics! 100k service/refresh/restore, done.
Time to CLEAN!!! The cars are like, "sup bro, long time no see".
Engine: I know, the replacement Dinan vac hose is blue. But, (and more importantly) it's rated for oil/fuel/anything. Heavy duty stuff I sourced from Norfolk, VA's industrial section of town. (I'm not really one for car shows anyhow, haha)
All tucked away in it's home again.
