I have a 2000z28 will I see any improvements with either of these? Mods are Vig3200, Mac headers, freemods.

Thanks

 

absolutely....
those 2 (ls6 intake and ported TB) are two great bolt-on mods

you can look at anywhere from 12-18+RWHP between the two..

i got a about 8RWHP/8LBTQ with increase with an ls6 intake.. with no tuning and no PCM learning time

 

the ls6 intake is definitely worth it. for throttle body, dont buy one just port the one you have.

 

Right, don't spend the money on a new TB, just port your own. Get the LS6 intake. It'll net you good gains now, and bring you more gains if you add H/C, etc.
