I have a 99 gtp. Mods are 3.4 pulley, DHP pcm, U bend delete, TB spacer, and a CAI. I want to run autolite plugs but not sure if i should run 605,s or 104,s. Basically wondering if I should going two heat ranges coulder or one heat range colder at this point. Any advice would be appreciated. Thanks.

I wouldn't. Not with the mods you have. 605's and 104's should be fine.

Good luck
