Hey everyone, I just recently bought a 05 mustang GT, basically stock except it came with a Steeda CAI / 90mm kit and Flowmasters axle backs.
What I'm trying to figure out is that, as far as I know this CAI kit thats on the car requires premuim octane plus a tune and also If I'm not mistaken come with the SCT tuner itself. otherwise it would definitely throw a code/ check engine light on.
But when I bought my car, it never came with a tuner nor threw a check engine light/code the entire time I had it and now. so I'm wondering is it possible that my car already has a preloaded 93 Tune installed? because prior to this I put 87 octane in the car due to the fact I didn't realize at that time my CAI required premuim fuel and also created noise at higher RPMs, so do you think my car already has a tune in it? any input would be appreciated.
