So yea, finally after dreaming of having a nice and quick car, it's happening. I'm accumulating parts as we speak. My best one to date is the MAFT Pro. Now I'm still reading the manual onthis thing and some threads around here, but I have one question for you guys. With MAFT Pro in speed density mode, will I need a fuel cut defencer or similar device? I'm going to keep searching but my time is limited. I thank you guys for all the help you have given me in the last year or so i've been on here.
