Here is my 2004 6.0 4l80e with 219 226 525 112 i had the same problems.. this is what i did to fix, too hard to explain it, so use my tune as a compare file ..
thank you the engine sounds alot better but if i go to reverse or any gear rpms still drop very low and i keep gettinng p1689 torque dileverd circuit
What converter do you have?
Is the cam and converter new? Have you re-tuned the base idle airflow for P/N and in gear?
2004 GMC Sierra 2500HD 6.0/4l80E
converter is a brand new 2500 and cam are new yes i have will post the new tune
sorry 2000 rpm b&m holeshot12483136_1055733054448473_1103346918_o.jpg
ass soon as i put it into drive the car shuts down the rpms fall to low and i keep geting those codes and randome missfire the silverado used to have 5.3 and i swaped it for 6.0
found a video series for ya might help https://www.youtube.com/watch?v=5A5U8mIgCU8
also if you changed any of your trans parameters, change them all back.. and start clean..
but this video should help you with idle
peace
