Less is more...

Yeah, they're both aftermarket engine management systems intended to replace your original ECU.
The benefit is that they allow you to completely mess up, erm I mean tune, your spark and fuel

Unless you're going to make heavy engine mods, go forced induction, or just like to spend endless hours tapping numbers into a lap top I wouldn't bother!

Saying that, I probably will replace my OEM ECU post-IVA, but mainly because I'm a bit of a masochist and like playing around with electrickery

I have lost count of the cars I have tuned and ended up over doing it. N/A wants to be kept to a mild cam, sensible comp ratio and a well sorted ignition/fuel set up. That way it keeps the all important driveability and remains useable on pump fuel. If you want more, turbo is the only way.

Just a thought,
My old Subaru Impreza WRX (as my avatar) had some fancy fuel management system and was pumping out around 350BHP, it had a "Dual map " setup where i could use on one setting for "Road" (mild boost) use and another setting for performance (WILD boost) including launch control etc .

Could something like this be implemented into one of these Fuel management systems that have been mentioned.
Would probably only realy be worthwhile if the motor was turbo'd .
