First off I'm running a x3z cobra ecu. No judging we all make mistakes lol. But heres the question I've never done diy tuning but I would like to learn I was gona get the SCT but found out I can control evreything for around $100 more with the QH. The megasquirt is to much so I don't want to hear about it. Is self tuning that hard to get into that I would be better off to go SCT? And how limited would I be on dyno tuning with the SCT versus the QH. I'll start off with that even tho I have a million questions.
