About the American naturally aspirated V8 (GM 5.3 / 6.2 Vortec and LS, Chrysler 5.7 / 6.4 HEMI)
The large naturally aspirated V8s of the Chevrolet Camaro, Corvette, Tahoe, Silverado, GMC Sierra, Yukon, Dodge Charger, Challenger, Durango, Ram and Jeep Grand Cherokee produce 300 to 485 hp. They are durable, simple, torque-focused engines.
How a Stage 1 remap works on the Dodge Ram 5.7 Hemi V8 396hp
On a naturally aspirated V8, Stage 1 re-tunes ignition advance, fuelling, throttle and, where fitted, variable valve timing; cylinder deactivation (AFM / MDS) can be disabled in the same calibration if wanted. The gain is measured, but throttle response and mid-range fullness improve clearly.
Pre-remap checklist
- Lifter and camshaft wear in the AFM / MDS cylinder deactivation system (known issue).
- Ignition coils and spark plugs.
- Exhaust manifold bolts and leaks.
- Automatic gearbox oil service.
This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.
