2005 GTP
I'm installing ZZP headers and catted downpipe with 3in exit to ZZP resonator and ZZP catback, and I already have the CAI, and autolite 605's
With the above mods and stock pulley, should I stick with the autolite 605's, or can I go to the 104's?
Next up:
3.4 or 3.6 pulley?
Autolite 605 or 104 plugs?
stock or 180 tstat?
Anything else while I have everything torn apart?
