Description
Dodge Charger SRT8 6.1L HP Tuners Stage 2 Custom Remote Tune — Heads, Cam & Stroker
A fully custom HP Tuners calibration for your Dodge Charger SRT8 6.1L 6.1L HEMI, written by N2 Speed for naturally aspirated builds running heads, a camshaft package or a stroker motor. This is not a canned file: we build it around your VIN, your modification list and the fuel you actually run, then refine it from your data logs.
Who This Stage 2 Tune Is For
Stage 2 suits naturally aspirated builds running heads, a camshaft package or a stroker motor. If your build sits between two stages, email your mod list to sales@n2speed.com before ordering and we will tell you which package to buy.
Expected Gains
Typical results: 70-120 hp with a cam package, cylinder head work or a stroker build. Gains vary with modifications, fuel quality, altitude and ambient temperature. We calibrate for reliable, repeatable power — not a dyno number you cannot drive.
What We Tune
- 6.1l spark and fuel tables, the aggressive srt throttle and torque management strategy, closed-loop fueling, cooling fan and rev limits, and w5a580 5-speed shift firmness and part-throttle behaviour
- Wide-open-throttle and part-throttle fueling
- Ignition timing with knock-safe margins for your fuel
- Throttle mapping and torque management limits
- W5A580 5-speed shift points, firmness and torque limiting when transmission tuning is added
- Speed limiter removal, cooling fan and rev limit adjustments on request
Vehicle Fitment
2006-2010 Dodge Charger SRT8 6.1L HEMI (LX). The 6.1L uses the pre-2015 NGC PCM and flashes through the OBD-II port, so no unlock service or security bypass cable is needed.
What You Need
- HP Tuners MPVI4 with Pro Feature Set or another HP Tuners interface, plus 2 credits for this vehicle
- A Windows laptop with HP Tuners VCM Suite installed
- Ability to record and send data logs
- Wideband air/fuel gauge — recommended for this stage
HP Tuners Credits Needed
Credits are how HP Tuners licenses a vehicle. They load onto your interface and are spent once, the first time the module is read.
- Engine Only — 2006-2010 6.1L HEMI: 2 Universal Credits
The 6.1L SRT8 uses the W5A580 5-speed automatic, which HP Tuners does not license as a separate controller, so transmission work is sold as tuning labor rather than extra credits.
Credit requirements are set by HP Tuners and can change. If you are unsure, send your VIN to sales@n2speed.com and we will confirm before you buy anything.
What's Included
- One custom calibration built for your 6.1L HEMI and modification list
- Revisions after log review until the car is running correctly
- Direct email support with the tuner who wrote your file
- Turnaround: first file normally within 1-2 business days
Revision turnaround: Revisions are done in the order they are received during business hours. Set time frames are available with notice. After-hours and weekend revisions are done when available.
