Doing both sides at once is the point. A pump alone lifts the mid-range, injectors alone lift the top end, and only the pair takes the fuel ceiling off a stock or full bolt-on car across the whole rev range. It also keeps everything inside the factory direct injection system, so there is no meth tank to fill, no secondary port injection controller to wire in and no extra failure point sitting outside the ECU's own diagnostics.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStock-turbo and full bolt-on 2.3 EcoBoost Mustangs going for a full-fuel-system calibration in one visit\u003c\/li\u003e\n\u003cli\u003eOwners running pump E85 or a high ethanol blend as their normal fuel\u003c\/li\u003e\n\u003cli\u003eBuilds that want the fuel headroom without adding methanol or port injection hardware\u003c\/li\u003e\n\u003cli\u003eCars being tuned by a workshop that would rather set the pump and injectors up together\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat Is In The Bundle\u003c\/h2\u003e\u003cp\u003eYou get the fully welded stainless Standard Bore Plus HPFP with its mounting flange, low pressure fuel line, high pressure fuel tube and flange installation tool, plus four drop-in batched direct injectors, an installation guide and the injector data sheet. Batching matters more than it sounds: the four injectors are matched on flow, so the tuner is calibrating one consistent set rather than compensating for cylinder-to-cylinder scatter.
