Charger
Tuning Guide
The 4-door muscle car that out-drags sport sedans three times its price. Here's every tuning and upgrade path — from your first tune to a full widebody Hellcat build.
The Dodge Charger shares the LC platform with the Challenger but adds unique constraints: the 4-door body creates different rear quarter clearance for wide tires, the IRS rear (2011+) behaves differently from the Challenger's solid rear axle, and staggered fitment unlocks a specific handling character you can't get with a square setup.
Scat Pack owners will find the most complete upgrade path here — the 6.4L 392 responds exceptionally well to a full bolt-on + tune combination, and the base brakes leave serious room for improvement.
Top Charger Tuning & Upgrades
ECU Tune
A custom ECU tune is the highest ROI mod on any Charger. On the 6.4L Scat Pack, a quality tune alone adds 25–40 rwhp, sharpens throttle response, and opens the door to bigger supporting mods.

The Charger platform handles a staggered fitment very well — narrow front for turn-in, wide rear for traction. Understanding offset constraints with the 4-door rear quarter panel is critical before ordering.

Wide tires on the Charger require understanding IRS rear geometry (2011+ models) vs solid axle (2008–2010). Proper tire sizing unlocks both straight-line grip and corner stability.

The Charger's IRS (2011+) rewards quality coilover upgrades, rear alignment kits, and sway bar upgrades. These improvements transform the 4-door muscle car into a legitimate daily-driver track machine.
Suspension Upgrade TipsCold Air Intake & Exhaust
An intake and cat-back exhaust combination on the 6.4L 392 is a solid first step that adds sound character, improves throttle response, and opens up the engine for a tune. Paired with a custom PCM flash, this combo adds 35–50 rwhp on a properly set-up Scat Pack — making it one of the best value upgrade stacks in the muscle car market.
