I just read about this and they are saying its very easy to use and wire.

Is anyone using this?

 

I could find very little info in the fbody world.. Do you know the aprox price of the xfi?.. I'm looking for a f.a.s.t or similar based realtime solution also.

 

The Accel DFI GEN7 is much better than the old FAST system. I can't say much about their new XFI system as I have not seen it yet. But from what I have heard about it, their new XFI has similar options as the GEN7 DFI. When the Gen7 DFI system came out a couple years back, it left the FAST system way back in the bleachers. While it is a decent system the FAST is more compatible to race or off road only usage. While the DFI system can be tuned to near OE drivability as it has far more tunable parameters than the FAST system does. From what little I have read about their XFI system, it appears that they have made a compatible product to compete with the DFI GEN 7 system. If you want to spend more $$$ then look at the BIG Stuff 3 system. That system has even more options than either the Accel or the XFI systems.
