hey guys, first off im new here just signed up today but ive been around the forum a lot.
i need some help with something though, i have a 2001 f4i with erion racing slip on only that i cut exactly half off of and im about to install a K&N air filter and im curious what map i should run? they do not have one on their website and unfortunately i do not have the money to get it dyno tuned
any input will be greatly appreciated.
thanks!
