whats the difference and does it matter which one you have?

 

The missing link is just a valve used the bleed off boost so your MAP sensor does not see positive manifold pressure and throw a MAP code. It can be used in conjuction with an FMU or AFC(not afc hack though).

The Greddy blue box is a piggy back unit that splices directly inot the ECU harness. No need for an Missing link with blue box.

 

so is one better than the other?

They can't be compared together. The Missing link is used to bleed of boost with the use of an FMU or AFC(not hack). The FMU is what is providing the fuel, not the missing link, it is just there to bleed the boost and not throw a map code.

The blue box uses the Honda ECU to manipulate the MAP voltage and provide fuel.
