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.

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.

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.

A boosted GM Gen V LT engine can run out of fuel in three different places: the low-side supply, the cam-driven high-pressure pump, or the direct injectors’ usable injection window. Learn how to read the log, identify the first limit and choose the upgrade that actually solves it.

Pump-labeled E85 can range from E51 to E83 as seasons and regions change. Learn what that variation means for octane, fuel demand, injectors, pumps, flex-fuel tuning, and safe performance.

Some bolt-ons are safe to install and enjoy. Others can create lean fueling, knock, misfires or unnecessary risk before the first hard pull. Learn what actually needs tuning—and what usually doesn’t.
