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
Roots-style (Whipple, Magnuson, Edelbrock, Sprintex) 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.
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: 2005–2010 Chrysler 300 uses an unlocked PCM; no PCM unlock required for this generation.

What to Know Before You Buy
Tuning & PCM (2005–2010)
2005–2010 Chrysler 300 5.7L Hemi uses an unlocked factory PCM — no PCM unlock required. ProCharger uses DiabloSport; Edelbrock and Vortech use their own calibration. ProCharger: request your tune before installing — email 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. Installing a Complete Kit on a modified car risks lean AFR and engine damage. See our Buyers Guide for the full breakdown.
CARB & Emissions
ProCharger HO Complete is 50-state CARB certified for this application. Vortech and Edelbrock vary — check EO numbers per product. Off-road-only kits cannot be registered in California. All Complete kits require 91 octane minimum. Standard warranty is 1-year; 3-year and 5-year extended warranties are available through most manufacturers (purchase separately).
Installation & Lead Times
Professional install recommended (8–14 hours). Budget for dyno tuning, fluids, and alignment. Lead times: ProCharger ships in 1–2 business days. Vortech: 10–12 weeks. Edelbrock: varies. ProCharger and Vortech do 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
What’s the difference between Roots and centrifugal superchargers?
Roots (positive displacement) units like Edelbrock deliver more low-mid range torque and instant throttle response. Centrifugal units (ProCharger, Vortech) build power toward mid-high RPM and often produce more peak horsepower. Both add significant power; choose based on driving style. See our Supercharger Buyers Guide for details.
Do I need a Complete or Tuner kit?
If your 300C 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.
Which kit fits my 2005–2008 vs 2009–2010 300C?
ProCharger and Vortech cover 2005–2010. Edelbrock Stage 1 covers 2009–2010 only. If you have a 2005–2008 Chrysler 300C 5.7L, choose ProCharger or Vortech.
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.
