I've got an 03' Xb9 that I have put a 12 Throttle body in. What is the best way to go about tuning it? I planned on getting ecmspy and doing it myself with some data logging. I've never used ecmspy before so am I bitting off more than I can chew? I'm open to other options so let me know what you guys think.
