ordering the final pieces... got ???'s

--------------------------------------------------------------------------------

ok,

here's the short and skinny,

I have a 2005 (LS2 M6)
will be installing Cam (226/226 591/591 on 112lsa)
Kooks Long Tube Headers (With Catted Connecting pipes)
and running HP Tuners

along with that,
I am having the shop modify (for use on the LS2 GTO)
the NX "NXL" direct port kit 80 shot
I already have th kit

I am ordering the accessories whenever Nitrous Outlet opens up again (it's thanksgiving morning right now)

what's the difference in the:
ZEX-82001: Racer’s Tuning Kit $332.53
NX-GEN-X GEN-X Upgrade $ 343.20
NX-GENX-2 GEN-XII Upgrade $ 447.92


I know the GEN-X dosn't have the purge,

is there any reason I should go with the GEN-xii insted of the Zex?


I am also intending to order hte GTO fold up switch panel, digital dual window switch, and the remote bottle opener from NX


is there anything else I should be looking at?

Nice set up. Don't think you missed anything. Post some pics.

 

anyone know if the Zex kit will give me everything that the GEN-Xiii kit has?

I like the idea of saving a hundred bucks.

 

They are both good kits. I prefer the NX. Maybe it's the color.
