yeah you'll either need a mapclamp or safc/dtec to control the fuel. The thing that's kinda got me worried is you've got all the fuel mods necesary to make good power except for the injectors. You're an 04 so you've got the S1 injectors but if at all possible I'd say may step it up to S2 injectors if possible. Other than that, yeah no matter what you do if you're upping the fuel you'll have to control it somehow
