I run the map ecu, love it, tuning is super easy (this is the first tuning attempt in my life), installation was easy, now its cheap (i was one of the first 5 that bought it and paid full msrp of $750 back then, now you can get them for about $350). I am seriously thinking about getting the map ecu II because it has timing and boost control. but waiting on my engine to be completely done before thinking about upgrading something that is sufficient for now.
