I am kind of new to this muscle car stuff so don't beat me up too bad. Just bought a 2011 Mustang GT. It Is equIpped wIth AJ LT carbon cold aIr Intake, magnaflow catback competition exhaust, and 3.73 rear end gear. Was hoping someone could help me With the setup of global spark and RPM settings and any other settings I may need to add.

Did it come with tunes preloaded? Honestly I wouldn't mess with those settings if I were you. Can cause your car to run really bad of you don't know what you are doing.

It did not come with any preloaded or custom tunes. Ive only added components that are bolt on in the tuner but have not altered anything else. Ive seen posts of people changing rev limiter and idol rpm. Thats what i was curious about. Tech at Dallas Mustang said that preloaded tunes from american muscle was only a sales ploy and that it should be put on a dyno. Im not racing it I just want the best performance out of it for what is on it now so I dont feel that it would be worth the cost of putting it on a dyno.

I'm not sure how to alter the values of the governor or rev limiter but I do know that the Bama tunes from AM are while mild but no sales ploy. I have an SCT/SFX3 tuner tuned by Bama.

My suggestion would be to contact AM either through this forum or by phone and have them write you a new tune with the adjusted values you are looking for.

But I know you want to learn how to adjust that stuff yourself and for that I applaud you for I am too chicken to mess with the settings myself. Lol

I know people on here do make these changes themselves but I can recall whom. Maybe they'll chime in.
