fast xfi or bs3?
 

which one is a better more user friendly system? Im building a twin turbo small block and have no tuning experiance so it needs to be somewhat user friendly.

thanks

We use and sell both FAST and DFI. We sell BS3, but have not used it yet. DFI seems to be the eaisest with its Q and A to help you programing. FAST is not to bad either. But especially for a forced induction car, I would count on using a proffesional tuner.

We are using DFI on Lisa's EmptyNest Project, so that pretty much tells you where we are leaning these days.
