i have a 99 silverado i am going to full flash a 02 4.8 tune i got off holden crazy. so far i see i have to disable a terminal f code. but is there anything else? someone told me maybe my injector tables. my stock tune shows i have 21lb and the 02 shows 25lb under the flow rates. so im just wondering what exactly in the tune needs to be changed. i really searched for about a half hour but nothing was really said. thanks

 

Complete reflash and then just change your injector data in the new tune. It's very simple.
