Technical Foundation
Complete vs Tuner Kit & Roots vs Centrifugal
Understanding these two concepts will help you choose the right kit. Our Supercharger Buyers Guide covers this in depth; here’s the essentials.
Complete Kit vs Tuner Kit
A Tuner Kit is the supercharger hardware only. It does not include: larger fuel injectors, upgraded MAP sensor, fuel pump (or booster), handheld programmer/flash tool, or the supercharger tune. Those components are 100% necessary to run safely. You must supply them yourself.
Tuner Kits are for (1) custom builds where you want different fuel/tuning components than the manufacturer provides, or (2) vehicles with long-tube headers, aftermarket cam, or forged internals. The basemap tune in a Complete Kit is calibrated for factory exhaust manifolds and stock internals. If you install a Complete Kit on a truck with headers or a cam, the vehicle will likely run too lean — risking catastrophic engine failure.
A Complete Kit includes fuel injectors, MAP sensor, fuel pump upgrade, flash tool, and tuning. It’s 100% bolt-and-go for stock or lightly modified Ram 1500s (intake, cat-back, throttle body only). No additional parts or custom tune required.
Roots vs Centrifugal
Roots-style (Whipple, Magnuson, Edelbrock) superchargers mount in the intake manifold. They deliver more low-mid range torque and instant throttle response. They also produce more “whine” at idle. Best for drivers who want immediate punch off the line and strong towing torque.
Centrifugal (ProCharger, Vortech, Ripp) superchargers mount off the side of the engine via a bracket. They build power toward mid-high RPM and often produce more peak horsepower. Both add significant power; choose based on driving style. Most Hemi Complete kits run 6–7 psi boost. Note: Long-tube headers reduce back pressure and can drop boost by ~1.2–1.5 psi; that’s why Tuner Kits (with custom pulley sizing) are recommended for modified builds.

What to Know Before You Buy
E-Torque vs Non E-Torque
2019+ Ram 1500 5.7L Hemi is offered in two variants: E-Torque (mild hybrid with belt-starter generator) and non E-Torque (conventional). Supercharger kits are engine-specific. ProCharger and Whipple E-Torque kits fit E-Torque models only. Whipple Gen 5 fits non E-Torque only. Verify your engine type before ordering. 2019-2022 models with GPEC2A require unlocked PCM; Whipple includes HP Tuners unlock. 2022-2024 GPEC5 is not yet supported by Whipple E-Torque.
Tuning & Unlocked PCM
ProCharger uses DiabloSport; Whipple uses HP Tuners. Critical: ProCharger requires you to email them your backup tune and head unit serial before installing. They send the supercharger tune via email (24–48 hrs). Do this first or your truck will be down waiting. Whipple includes HP Tuners RTD flash tool and PCM unlock service (ship PCM to HP Tuners). Add NGK LFR6AIX for ProCharger; Whipple includes 1-step colder plugs.
CARB & Emissions
ProCharger HO Complete is 50-state CARB certified for Ram 1500 5.7L E-Torque. Whipple Gen 5 (non E-Torque) is CARB legal for 2019-2020 (D-231-85); 2021-2022 CARB pending. Whipple Gen 6 E-Torque is CARB EO D-231-115. Off-road-only kits cannot be registered in California. All Complete kits require 91 octane minimum. Standard warranty is 1-year; extended warranties available through manufacturers.
Installation & Lead Times
Professional install recommended (8–14 hours). Budget for dyno tuning, fluids. Lead times: ProCharger ships in 1–2 business days. Whipple: 14–16 weeks (built-to-order). ProCharger does not include 1-step colder spark plugs; add NGK LFR6AIX. Hemi engines use 2 spark plugs per cylinder (16 total); order quantity 4 (boxes of 4).

Common Questions
Frequently Asked Questions
How do I know if my Ram 1500 has E-Torque or not?
E-Torque Rams have a belt-starter generator (BSG) on the engine. The easiest way to confirm: check your VIN or build sheet, or look for the small electric motor/generator unit on the front of the engine. ProCharger and Whipple E-Torque kits fit E-Torque only. Whipple Gen 5 fits non E-Torque only.
What’s the difference between Roots and centrifugal superchargers?
Roots (positive displacement) units like Whipple deliver more low-mid range torque and instant throttle response. Centrifugal units (ProCharger) build power toward mid-high RPM and often produce more peak horsepower. Both add significant power; choose based on driving style. For towing, Roots-style can be advantageous.
Do I need a Complete or Tuner kit?
If your Ram is stock or has only simple bolt-ons (intake, cat-back, throttle body), get a Complete kit — it includes fuel injectors, MAP sensor, fuel pump upgrade, and tuning. If you have long-tube headers, a cam, or forged internals, you need a Tuner kit with a custom tune.
Will a supercharger void my warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty for aftermarket parts. However, powertrain claims related to forced induction may be denied. Some manufacturers offer supplemental warranties.
Why does ProCharger say to request the tune before installing?
The ProCharger tune file is not pre-loaded on the DiabloSport tuner. You must email ProCharger your backup tune and head unit serial; they reply with the supercharger tune in 24–48 hours. If you install first, your truck will be down until the tune arrives. Do this step before you start the install.
What fuel do I need?
All Complete supercharger kits require 91 octane minimum. Higher octane (93) is fine and may allow slightly more aggressive tuning. Whipple Gen 5 power numbers are quoted on 93 octane.
