Corvette owners in here!! got some ?'s

[red04svtcobra]

My dad just bought a 99 C5 corvette and was told it has the Z51 package, how can he tell it has it? Also what mods can he do to it for performance but not need a tune? I was told he could swap out the air intake box with a Z06 one as it is less restrictive.
Any other tips you can provide please chime in, thanks!!
Here are some pics of it.

Easiest way is to read the RPO code sticker.

2nd easiest is look at the sway bars.

Bushings and bars have white paint marks on them. (Standard is orange)


This will give you all the differences.
