I need to replace my spark plugs anyways. But since I will be getting a tune soon. Should I go with 1 step colder nickles, or just get new stock plugs?

If you're not going with a bigger turbo (to make more power then Stage 2) go with the stock plugs. Generally speaking, 100hp over stock needs a colder plug.

Sweet, thats kinda what I thought. Thanks for the info. :)
