S&B 52 Gallon Tank Upgrade

[rtrthebear]

Good evening, I am new to the forum and hope to find some help. I was reading in past post but haven’t found updates as of yet. I am wanting to upgrade my fuel tank to a higher capacity and am trying to find out if anyone has found a way to correct the DTE and the fuel gauge to read correctly through AlfaOBD. Thank you all for your help. 2017 Ram 3500 Mega Cab is the truck I am looking to upgrade if possible.

The DTE correction wasn't an issue on my '22 2500. I just changed the fuel capacity to 194L with AlfaOBD. The biggest issue is the fuel level sending unit doesn't work well with the extended depth of the new tank. At 3/4 on the gauge I can add 30 gallons. 10 gallons will bring it to Full, the additional 20 gallons is beyond the range of the sending unit.
