p59 pcm 4.3 to 5.3 dbc conversion. idle stumbles when cold and also hard acceleration

[71k3500]

hello, when cold start the idle stumbles if you try to accelerate. after it warms up normal acceleration is fine. but if you hammer the throttle it will fall on its face. im thinking fuel starvation? its a stock 2002 5.3 parameters tune for dbc. any help is appreciated.

it seems to be getting better as i drive it a bit. is it learning?

are your o2 sensors hooked up and working? any exhaust leaks? we will need a log also to tell anything.
