  • Out of the box tune

    Anyone ever use one of the hand held tuners and an "Out of the box" tune on a 2010 Shelby ? How did it work. The car is box stock with 27,000 well cared for miles. Do you really get that much extra HP and torque ?

    I would suggest at least getting some datalogging while on a dyno and having the tune developed from that information rather than using a generic out-of-the-box tune. Many times those seem to (or at least used to) tend toward leaning out the A/F ratio more than might be desirable.

      Reads like the same thing as a Hypertech Power Programmer. They were junk so be vigilant.

        I used one for my 2000 GT when it had just bolt ons. Air/Fuel was 14.4:1. I wouldn't trust them based on my experience. Just get a real dyno tune

          Definitely not too lean. Maybe it was timing advance that the out-of-the box tunes used to rely heavily on.

            Lots of good tuners out there who have tunes that will be safe, but at the same time a mail order tune might be leaving some on the table.


            John Lund and VMP racing offer great mail order tunes. If you tell them everything you have as far as mods they will be able to work it out. You will pick up a lot of power even if your car will be tune only. Adding a intake and ORX/H and a pulley will gain you a lot of hp.

              The car now is totally "Box Stock" just like it came from the factory. Would I gain enough to notice if I did NOT do anything else to the car ?
