Opinions on DFI Systems...

[DemonTSi at aol.com]

What do you guys think of the following systems:
- Electromotive TEC-II
- Accel DFI
- Racetech SDS
- Haltech E7 (I think it was the E7....the one with both fuel and ignition
control)
- anything else out there....
Any comments, thoughts, problems, etc...?

Oh yeah, another thing: When injecting NOS via direct-port fogger into a PFI
manifold...would it be better to run the NOS fogger before or after the fuel
injector? 
Thanks guys...
