Hi I am about to purchase a link G4 plus ECU the problem I’m having is contacting and finding a good mapper for my Subaru I’m running a 2.5 semiclosed deck fully forged capable with supportive modifications for 500 hp I am looking to run around 430 to 450 mark as I am finding with standard ECU it is not very Smoove so that is why I have decided to go with the link any help would be appreciated
