I read through your thread and judging off you experience I'd definitely say the quarter horse is the way to go for you. Assuming I just wanted to use the factory ecu with something like tuner pro what all would be required? I'm assuming the quarter horse, some files and a laptop but is there anything else hardware wise? I hope all that makes sense it's been a long day.You know my vote is for the quarterhorse
Sct is ok, too. But I love the real time tuning of the QH.
