Description
Dodge Challenger SRT8 6.1L Diablosport Stage 3 Custom Remote Tune — Supercharged, Turbo & Nitrous
A fully custom Diablosport calibration for your Dodge Challenger SRT8 6.1L 6.1L HEMI, written by N2 Speed for complete builds with a supercharger or turbo kit, including a dedicated nitrous map. 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 3 Tune Is For
Stage 3 suits complete builds with a supercharger or turbo kit, including a dedicated nitrous map. 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: 150-300+ hp on a supercharger or turbo kit with supporting fuel. 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
- A dedicated nitrous map on request, built for your shot size and fuel
Vehicle Fitment
2008-2010 Dodge Challenger SRT8 6.1L HEMI (LC). 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
- A Diablosport handheld — the Diablosport inTune i3 Platinum or Diablosport Trinity 2 — which you can add below
- No credits and no laptop required: the file loads straight from the handheld
- Ability to record and send data logs from the device
- Wideband air/fuel gauge — required for this stage
Why Diablosport on a 6.1L
The inTune i3 and Trinity 2 both flash the NGC PCM through the OBD-II port and keep a copy of your stock file on the device, so returning to stock is a two-minute job in your driveway. If you would rather have full table-level control and data logging, buy the HP Tuners version of this same stage instead.
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.
