I don't think SD will make anymore power vs MAF on my car. I have it tuned well with the MAF, I'm satisfied with how it runs. I just wanted the antilag for the dragstrip. I'm not a noob, I know how hard it is on parts. But it will only be on for a few seconds at launch and shifts, it's a risk I'll take. I had my rom about ready to flash the other night and romraider crashed, I need to remember to save my work more often.
