Sorry group if this has been covered before but I am a newbie...I have seen a couple of companies selling engine management chips and would love to know if there is anything out there that actually works. Currently running a K&N filter with zero noticeable change. Looking for horsepower and better mileage...HA! Who isn't??!!
