I am running the EDGE EVO and a K&N intake, I am having problems with level 1..when I stomp on it the rpms go up but it does not accelerate as it should, and on level 2 at a constant rpm I can hear my intake flutter up and down and watch my tach go up and down 20-30 rpms. It drives me crazy!! If anyone else has had this problem I really need the help because my stock intake tube is cracked and I can not go back to stock untill I find a tube.
