I haven't bought it yet, need to talk to the sales rep first.
The Fast system seems nice but it is out of my price range. The Fast System would cost 2 or 3 times as much as the MS2. Still not sure how it will tune itself with a Boosted application though. There are some very good review's for the MS system. I think it should work out just fine for what I am doing, we shall see!
I am going to buy the one that needs to be assembled. This should help me understand how the system works from top to bottom before the engine goes to the dyno.
