Hello guys I have a simple question, my 2012 mustang gt is dyno tuned by a company and i asked them to lower my rpm shift from 1-2 but they just send me an "open" file were I can adjust it how ever I want .. that's great if I knew what the hell I was doing . So here is my question my car is shifting 1-2 around 2100-2200 rpm which it feel like it takes for ever I want to lower it a little but dont know how to adjust it . Do I do shift press -5 -10-20 -25 ? Or is it +5 +10 ext .

Who is your tuner and what device are you using to adjust your shift RPMs?

I could be wrong but I don't think you can change shift RPM with the x3 handheld. What you are referring to is shift pressure, which will only adjust shift firmness.

I would call your tuner and describe what you are trying to accomplish. You would have to get into the part throttle tuning tables which I have no idea on and you cannot access that via the handheld.
