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 car 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 vehicles (intake, cat-back, throttle body only). No additional parts or custom tune required.
Roots vs Centrifugal
Both kits in this guide use centrifugal superchargers (ProCharger P-1SC-1, Vortech V-3 Si) mounted off the side of the engine. They build power toward mid-high RPM and often produce more peak horsepower. ProCharger is FastHemis’s preferred centrifugal brand for most Hemi applications. Most Hemi Complete kits run 6–7 psi boost. Note: 2005–2008 Magnum uses an unlocked PCM; no PCM unlock required for this generation.
Important
What to Know Before You Buy
Tuning & PCM (2005–2008)
2005–2008 Magnum has an unlocked PCM. No PCM unlock required. ProCharger uses DiabloSport handheld; Vortech uses DiabloSport Predator. Both Complete kits include tuning. Critical for ProCharger: Request your tune before installing. Email ProCharger your backup tune and head unit serial; they reply in 24–48 hours. The tune is not pre-loaded on the handheld.
Complete vs Tuner: Which Do You Need?
Stock or simple bolt-ons (intake, cat-back, throttle body)? → Complete Kit. Headers, cam, or forged internals? → Tuner Kit with your own fuel system and custom tune. ProCharger offers both Complete (1DE314-SCI-5.7) and Tuner (1DE304-SCI-5.7). Vortech offers Complete for this application. See our Buyers Guide for the full breakdown.

Common Questions
Frequently Asked Questions
Do I need a Complete or Tuner kit?
If your Magnum 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. ProCharger offers both.
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.
Which kit is 50-state legal?
Both ProCharger and Vortech Complete kits for the Magnum 5.7L are 50-state CARB certified. Vortech is certified under CARB EO #D-213-31.
Why does ProCharger say to request the tune before installing?
The ProCharger tune file is not pre-loaded on the DiabloSport handheld. 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 car 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.
