p59 pcm os 12587603

i have a 2004 silverado 1500 4x4 4.3 v6 4l60e truck. i did a 5.3 swap with an 04 5.3 but used a dbc tb and intake since the 4.3 was dbc already. i am looking for a 5.3 4l60e drive by cable stock tune. i know the vans can support the iac and tps but have not actually found a van tune that is dbc. any help plz.

First off, wrong section. As long as your pcm has the the iac drivers in it(find recent post with list of service numbers in gen 3 section) you just have to change the system options and a few dtc's and it will work.
