I've just bought a 2.0 legacy GT bought from a salvage auction, it's got a splitfire supershot bt module, I'm not 100pc sure what it does I done some research and what little information I could find its an ignition amplifier or something like that, should I remove and toss in the bin or are they decent?

 

Bin

 

Can they cause issues then?

 

Only bling doing nothing.
