If I was to put 1.7 ratio rockers and a fastman throttle body on a 5.2 should the computer be reprogrammed or will it still be able to compensate for the exra air from both the rockers and the throttle body.

 

if u dont reprogram it will learn around 200miles i belive, but u can disconect the neg. cable and then turn key on first notch for like 10 seconds, shut it off and reconect .... i think thats how it works, i havent tried it only read about it.
