Bought a used SCT Tuner... need help understanding something
I purchased a Steeda CAI and SCT SF3 (the tuner says SF3, but the box says X3 so I have no idea) from somebody who owned a mustang on craigslist (same as mine, 2006 gt), and I'm still a little confused as to how they work exactly.
I tuned my car to work with 91 octane & my CAI, and it's been running fine since. The tuner has an option for "Brenspeed Custom Tune", but I'm assuming that's a tune he received/purchased that came with the tuner when he bought it.
Am I in the clear since things have been running fine? Or do I still need to get a custom tune from brenspeed/AM?
Even though the tuner was unlocked and married to my car, am I still using a tune from the previous owner?
Are the strategy tunes & custom tunes completely different from each other, and the strategy tunes stay locked to the device?
Thanks guys, I'm just trying to clear up some confusion haha.
