The FAST 8- stack system comes with INGLESE 8- stack; the TB might be from Borla or others, but they do have the Inglese- name on them.
The EZ-EFI system might be good for those who do not want full tunability and no opportunity to log what's going on in the system. If you are up to some "real" performance, you'll ned the FAST XFI system.
The XFI system have alot of potential and gives the possibility to tune whatever your needs are. It is NOT very complicated either; easy to understand menues and nice software.
The EZ EFI do have som pitfalls (as do most systems!) so I advice you to read up at
CPGNATION.COM It's a brilliant "tool" and gives alot of help.
If you choose an 8- stack system and if you want any other tuning strategies other than alpha-n (fuel VS tps) and want good driveabillity on the street, I suggest you choose to plumb the underside of the inlet (valley pan) with vacum lines to a MAP sensor. You can even double it and make a IAC motor connection to the TB's. (As I understand, it's not wise to plumb the IAC and MAP in same curcuit. But it should be possible to use the MAP curcuit for power brakes..(?))
I've installed FAST system with LSx- coils (distributorless) on my 347 stroker this winter, and got it running really well. With a setup like this, you could have the coils tucked away in the inner wings or frame on your Cobra.... Would be neat!
I'll do a write- up on the system soon.
