A flex-fuel sensor tells the ECU what is in the tank, but safe performance depends on fuel-system capacity, injector headroom, pressure control, calibrated timing and boost blending, and fault protection. Here are seven checks that matter.

Wisher Performance has released AuxJection for the 2022-2026 Cadillac CT5-V Blackwing. Here is how the factory-ECU-integrated supplemental fueling system fits ethanol, pulley, intake and supercharger builds, plus what to verify before tuning.

Two 550-hp Dodge Charger SIXPACK Scat Packs were transformed into 750-hp drift cars for Roadkill Nights. The builds reveal why boost control, fuel delivery, heat management, driveline capacity and chassis setup all have to advance together on a serious turbo build.

PRI recently spotlighted Stanadyne's 150-year anniversary. We look at what the company's modern RGX 12mm high-pressure GDI pump means for boosted and E85 GM LTx builds, why high-side capacity is only one piece of the fuel system, and how to validate the combination on the dyno.

SEMA’s 2026 market data says internal-combustion vehicles are expected to remain the dominant new-vehicle powertrain through the next decade. Here’s what that means for enthusiasts building boosted, fueled, tuned and track-ready performance cars.

Race fuel selection is about more than the octane number. Learn how AKI, RON, MON, oxygen content, ethanol, lead, stoichiometric ratio, fuel-system capacity and calibration work together.

A 415-LPH DW400 fuel pump is not a universal horsepower guarantee. We break down C6 Corvette fuel pressure, pump voltage, E85 demand, injector headroom and how to validate the complete fuel system under load.

Lambda keeps fueling targets consistent across gasoline, ethanol and changing E85 blends, but only when the wideband sensor, ethanol-content data and logger scaling are trustworthy.

A 1000cc injector rating does not tell the whole story. Learn how fuel pressure, boost, E85 demand, impedance, dead time, physical fitment and tuning data determine whether an injector is right for the build.
