Sorry to hijack your thread, I hope you are still around, catfish Hunter. The only issue I am having is for fuel gauge calibration. I have a 99 Yukon Denali that I have swapped in a stroked 05 LQ9 out of a Escalade. Been running fine for a couple years, but I cannot seem to make the 99 fuel gauge register properly. The only gauge in my stock instrument cluster that runs off the network is the fuel gauge. I have changed the instrument cluster type, the PWM enable flag, and all of the different scalars for fuel system, never seem to get it right. Any ideas, all help is appreciated
