Piggyback and injectors question... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I'm currently trying to figure out future options for fuel management, and I know that most piggybacks, like the SAFC-2 and Emanage, can only handle "a maximum 50% larger main injector correction adjustment." That means (from what I gather) for my RB20DET w/ 270cc's, it'll only be able to correct an upgrade of up to 400-ishcc injector size, and the closer that I get to that number, the less reliable the tuning will be.

So my question is, if I turn up the fuel pressure to.. oh say... 3.5bar instead of the stock" 3bar, and use 370cc's (equation here), so that the injectors are actually flowing like 430-ish cc, would the piggyback be able to handle it? I don't know if this is a dumb question or not... lol, I might just be overthinking, or um, underthinkng this...
