I have found a K&N FIPK2 system for a great price and I am wondering if a tune is required along with it or if it will just maximize the performance of the intake? If it isn't, is it pointless to just put the intake on and not do a tune and pulley? Which tunes and pulleys would you guys recommend? Is this a logical progression for the first performance mods? This is a great forum with a lot of good information-thanks in advance.
