Thread: kr.....ahhhh

i have a stock gtp all except for a intake behind the headlight and i had 4.5 kr so i swapped out for fome AP104 colder plugs and im still gettin 1.9/2.1 *of kr....what the hell lol do i need some exhaust mods that bad the car cant even handle the stock pulley or will a pcm take care of it?

2* on a stock pulley isnt a lot to worry about. i think your next step is a PCM, then a downpipe/headers.

should i have OVERKILL tune my pcm for the mods i have in my sig even tho they arent on yet?

tell him you have those mods and put in the pcm when you them installed. Just letting you know it will take a long time to get your pcm from will but, it will be worth it.

you could run a PCM with those mods stock. it will just run a little rich when in boost.

ok cool man thanks, this will prob eliminate kr too right?

yeah, when a car runs rich it helps keep down some of the detonation. but this is not the right way to kill knock because running too rich isn't good for the car.

could i have the KR because i went with platinum plugs instead of copper cores? or is the difference minimal....

eh, as long as the heat ranges line up then it should be money. copper are just cheaper.
