They’re working good?
Guess so. I had it backed into the garage while working on it and pulled it out, down my 110' driveway and turned it around and pulled it back up to the garage. Rear did feel stiffer. I'll feel the bladders in a couple hours and see if they are still firm.

Should I do a level control sensor relearn with the Tech2?

that might be a good idea, has to be parked sitting level, no one in the truck, you can just run the cable out the drivers window and do it while standing next to it.

You’re supposed to. It’s called ALC trim set I think.

What about gas? Should it be done with a full tank or? I currently have half a tank

Well, I’m back. Life has been crazy. Got sucked up by classes, BUT I just finished my second one, and the third doesnt start until tomorrow. Had time to get out HPTuners again, and started messing around with the 4L60e parameters. I followed a guide I found online, and boy howdy did it make a difference. It feels like an actual modern transmission now. It slips the clutches so much less taking off. Feels like its in a hurry now

Welcome back. Was wondering where you’ve been.

Glad to hear school is going well.
