I have 2006 M7 that is all stock with the exception of a can. I have a BDX intake for this sled and am just wondering if I need a fuel controler I really do not want to go this route. I ride at approx 3000 to 10000 feet and do not want to start to lose the reliability of stock either. If I put this on will I see any big gain or benefit and will I lose my reliability as well. Could really use help on this. Thanks in advance for any help.
