Use older FAST system or get the newer XFI?

I have a customer who supplied me with an older FAST system #30113010. Its all new and never installed. I was looking for some instructions online and didn't have any luck. WHile searching a read that they are no longer supporting this system. I'm concerned that if we do use this system that I might run into some problems because I do not have any instructions and since they no longer support it we may have to switch to a different system anyways. I figured the newer XFI system must be far superior if they aren't supporting their older stuff. Do you guys have any thoughts or suggestions? Is there another brand we should consider?

BTW. It's going on a small block Ford turbo motor in a mustang and I do have the software disc for it too.

The FAST classic is a great box and I keep one around to fire engines on the test stand, etc. The main tables are identical to the XFI so support, should you need it is there. The drawbacks compared to XFI are the fact that it is bank to bank, only supports one ignition style per part number, and has less outputs. The instructions and latest version of the software can be downloaded at the fuelairspark.com website. Look for C-com WP.

Are you making 600 HP or 1600 HP? Up to 2hp per cu inch I would not worry about using it.

Thanks for the input. It's supposed to make 947 hp at the flywheel but I wasn't told how much boost it took to get there. It's only 331 C.I.

I also got to figure out what type and size of injctors to run.
