ok guys just a quick update. ordering the zzp supercharger in a couple months but i have a quick question. if i put a bigger throttle body and cams and valve springs would i need a hp tuner? the charger comes with a modified ecu but im not sure it still be the proper air/fuel mixture after adding cams and what not...

 

You already have to switch to a lsj throttle body don't you? If you really want bigger then that ls4 is next and that needs some hp tuner work.
