thx for the update and resolution

on 2022 and newer you dont need the tool. put your truck in relearn and drive it for 10 to 15 miles and the sensors relearn the new position

be nice to know what vehicle you have

my 2014 is at 290k kilometers or 180 k miles and still going . all original except battery, shocks driveshaft and vacuum pump and 2 sets of brakes and rotors

since you have a 2019, did you ever have the transmission serviced and updated to the newest transmission fluid

Vince you will get some lift as i believe that chart is based on v8's, and the 2.7 is a lot lighter. also you have a 2wd with even less weight on the front end

if you have the Bose system you probably shorted the amp

i would let them do the flush, that way it is documented that you have a problem. then when your warranty is up you can still go after gm if there is still a problem

could try 2 inch drop spindles on the front and change the rear spacer block, would get you down to 4 inch lift

system reset and start over setting it up again

try cracking open the bleed screw a push it back in slowly

my dealership has a least 20 new 2023's on the lot, lowest price is 73k and up to 90k for a zr2. they keep bugging me to trade my 2020 in and i tell them no. trucks are going to drop in price because they are not selling in my area. they have not sold one truck in over a month and i think it's the interest rates that is causing it and over priced trucks.

your systems still point to a tire, i had michelins on my truck that where great until higher speeds and went thru the same as you did, eventually the tire exposed it self with a buldge in the tread. at lower speeds and even on the balancer it did not show that the tire had a separation going on inside of it

it is a process that all newer diesels have, it is a process where the system burns off particles and soot out of the dpf

the exhaust will sound different if it is doing a regen
