The ecu in your car has more safety barriers than felix trinidad's trainers. (PR boxing joke). Once the computer feels the motor is threatened it pulls timing which reduces your hp, and keeps your motor from harms way. The only disadvantage you will have while daily driving will be heat. Not overheating but just loss of hp if your temps get hot (middle way, car never passes a needle over middle). Depends on your weather. Winter here I can race all day and car runs strong. Summer is very hot, less performance. Either way with all the mods you want to do, your every day driver will still be a beast even with a loss of hp. I would mirror needswings setup if you are modding because he has thousands of dollars testing it, just to be safe for everyone. It's still a modification from factory but there are alot of daily drivers on here. The MB guys have been modding since this motor came out in 03'?? So far no one on either board has hurt the motor. I don't drive mine daily so I'm not much help with every day experience. It is new territory for everyone that mods this motor. We all hope they last years and years like the MB guys.
