Previous Owner Mods
Im new to this forum but not new to Mustangs. I recently purchased a 2012 GT/CS and I am trying to figure out the modifications the previous owner had made. (Looking to purchase the SCT x4 tuner) I know he did Roush Axle backs, Steeda CAI, JLT oil separator. The mid pipe is an X-pipe but I thought 2012 GTs had stock H-Pipes but the material itself matches perfect with the stock manifolds, I also dont see any markings on it. The gear ratio seems to have been changed also or maybe he purchased 3:73s from factory. These are the questions I'am trying to answer having gotten no where trying to track the guy down.
I dont know if this will work but could I purchase a Tuner (never purchased or tuned my car before) tune With the mods I know for sure have been modified/log the data and have BAMA check it out? I know if the gear ratio is off in the tune the speedometer will be way off, wondering if it would tell me anything else.
Any information would be helpful.
