Fueling Kit — B48
Fueling Kit — B48: the high-pressure pump, matched to a tune that uses it.
An upgraded high-pressure fuel pump paired with a calibration written around the extra fuel it can deliver. The stock B48 HPFP runs out of headroom before the rest of the hardware does on higher-octane or ethanol-blend fuel; this set raises that ceiling and ships with the tune already matched to it, so the pump and the calibration arrive as one decision rather than two guesses.
What's in the set
- Dorch Engineering B48 / B58 HPFP upgrade — a higher-flow high-pressure pump for fuel-limited builds.
- The matched custom BM3 calibration for your chassis, written to use the added fuel delivery.
Why it ships together
A bigger pump with no tune to command it does nothing, and a calibration that asks for more fuel than the pump can supply will pull timing to stay safe. Matching the two is the whole point of the kit.
The saving
8% under buying the pump and tune separately — the kit price reflects the matched build, not a discount gimmick. The savings indicator on this page shows the current figure.
One cart line; components ship as their individual SKUs.
Ships from Boca Raton, FL. Hardware components within 3-5 business days; tune license emailed after post-install datalogs.
Build a custom bundle.
Toggle on what's already on your car. We'll subtract those and price the rest as a bundle. Bundles need at least two parts left — if you've got nearly everything, the full kit above is already the right call.
Why one SKU, not a parts list.
Every kit is priced 8% under the same components bought separately — the standing rule on every kit we sell, with the exact figure for this one on the vs à la carte line in the panel above. The components are matched as a set, and the kit price applies only when they are purchased as one SKU.
We schedule installs at the shop for kit buyers in Florida. Out-of-state buyers can choose a Phantom-certified installer or DIY with our install instructions. The calibration is delivered remotely either way.
