pulley and supportive mods

If I wanted a 2.8-3.0 pulley, what mods would I need to keep KR down? CAI and cat-back exhaust be enough?

I run:
2.8/3.1 pulley
cam
cai
3" dp
3" cat
custom pcm
tb spacer
autolite 103's
water injection

still see some kr when not spraying, and sometimes while spraying. Im sure if i bought headers that would help.

Get the short stack intercooler. You injectors will be fine so you dont have to replace those. You may have to get bigger fuel lines but I am not 100% sure. Make sure you open up your exhaust delete your resonator if you havent already and unload that u-bend. I unloaded my cat as well. With my set up I see 0* KR and I dont even have rockers yet.
