I am interested in purchasing a quarterhorse tuner for my 90 mustang I am a little bit rusty on them and was seeing if anyone out there has one and can maybe help me get started and help choose the right products I need for it to work and be able to do live tuning thank you
and the other thing you would want is a wideband O2 sensor. I am planning on going with the quarterhorse soon, just have to get through the holidays. I haven't decided what wideband i am going to go with but i have heard good things about Innovative.
