Really a clean looking burb. Hope this is the fix Sent from my iPhone using Tapatalk
Glad you are getting there. TO bad it took this long a couple "tuners" to find issues.Try playing with the tank size. Mine still reads full OK, but starts to move slow then dumps. When the light comes on (rarely when going to NV to fill) I still 10 gal in there.Same with tire size, finally got it 1mph under, which I can live with.
Have you ruled out the stepper motor in the gauge cluster being bad? They’re known to do that.
The stepper motors just start acting “weird”. Not reading right when they always have before, going past their min/max, etc. The fact that it started happening right after you changed the tune is suspicious though.Like JR says, plenty of places that rebuild those clusters all the time. Now after saying this, yours is an 02 and might not be applicable given what I’m seeing here.https://www.gmgaugerepair.com/chevrolet-instrument-cluster-repair/digital-gauge-cluster/
The can bus communication protocol changed, which is why on later models you can drop in a later model engine and do a re-learn. 2001-2002 are the least compatible. Sent from my iPad using Tapatalk

H would slander Don with a full court media press aided by her cronies. Say that he beat baby seals for fun in Afghanistan. If that didn’t work, Don would die from some mysterious cause. Sent from my iPhone using Tapatalk
Square D all over,,,,,,,,ouch.Since everyone who knows anything is saying the TC is junk, send it back. Sure you can challenge the charge if they fight it. If not I can understand the 6BT, but why a 4L80? I keep thinking about keeping my 46R, but going with a tap shift.
Don I believe the Allison will fit behind it and be compatible with your controller system although only the five speed on your 2001 unless you do the 5-6 speed valve body upgrade. The 8.1 came with it. That would solve your trans/tc problems. Fuel mileage is still going to be a concern but should get better with less slippage.

Just to be the weird one in the group, I really don’t understand why you aren’t able to get better mileage out of it. I’m running the same engine(minus tuning, cam, supercharger and big tires). I regularly get between 12-14 mpg, and that is combination back roads and highway, with me sometimes making the kids happy when they say “go faster daddy”. Not to mention this is a 3/4 ton van with 500k miles on it. Something just doesn’t sound right to me. Maybe your transfer case is stuck in 4wd, maybe you’re just pouring gas on the ground when you are driving it around, but to me it seems illogical. Just my two cents from a Dave that served in the Air Force. Let the gaming begin. ;)Sent from my iPhone using Tapatalk

And 4:11 gears?Sent from my iPad using Tapatalk
Well I would expect a regear with the Cummins back to 411 to take advantage of the torque.Sent from my iPad using Tapatalk
