FAST or Aeromotive elec fuel kit?

I have been looking at FAST and Aeromotive fuel kits for an efi engine that will be turbo'd.

I downloaded both instruction forms and one is copying their copy from the other-the diagrams and warnings are identical in places.

What I'd like to know is, whats the difference in quality.

The Aero kit goes for $639.95 and is rated up to 1000hp turbo'd with 600lbs/hr

The FAST kit is $832.95 and is rated up to 700hp turbo'd

Is there a massive difference in quality for the price difference??

Please let me know what you guys think.

Thanks,

B
