I still can figure out why in the hell when I try to drive forward I have no throttle... it kicks in for half sec after I drop into drive then nothing I can press the pedal all day any only idle down the road... I have no idea what the issue is... I just really need some help...
Do you have the lightning bolt in dash?
Lower the throttle body airflow numbers by half .00 to .20
max demand throttle 700 rpm 0.84981684981685
See what that does.

No lighting bolt.
Those airflow numbers can do wierd things. During my tuning I've gotten the dead pedal and it came down to the airflow numbers, but I would get the lighting bolt.

I had a can issue and found the pcm took a shit so I got a new. But now I still have no throttle when driving. At idle in park the throttle is snapping hard and all the power. But trying to drive I got nothing....
Tried what u said. I have pedal for half a sec right after I put in drive then nothing. I can press the pedal to floor and no accell
Seems you have a few threads on the same build and same tune with different names? Looks like the people that know this tuning stuff helped you in other threads, not sure why they're staying away from this issue, I sure don't know enough to help.

start overv5.hptup and down but still no smooth throttle.hpl
attached a new tune and log
someone point me in a direction
just out of curiosity have you tried a throttle relearn and reset all adaptive?? Had the same issue one time when i installed my nitrous kit, had to unplug the throttle switch to get the input from pedal for window switch and had to do a throttle relearn for it to work right again. Might not work in your case just a thought.
Yes I have several times.
