I am not a GURU but I can give you a few opinion from what I have read on this forum.
Definitely a BIGGGG NO to fiveology. There has been nothing but issue with them on our trucks, if you back track.
FMS is a good product but considered old but good mass air kit, if you are not going too crazy with your motor set up. There is a better aftermarket product out there with better tune-ability and support.
