America's Remote Performance Tuning Specialists
N2 Speed is a professional computer tuning shop specializing in custom remote tuning, PCM and TCM unlocking, ECM unlock services, and high-performance upgrades. We tune Dodge Challengers, Chargers, Hellcats, Scat Packs, RAM trucks, C5/C6/C7 Corvettes, Camaros, and more. Our services include MDS delete tuning, speed limiter removal, ABS module programming, and NAG1 TCM programming.
We are certified HP Tuners and DiabloSport specialists with years of hands-on experience tuning American muscle.

Frequently Asked Questions
What is PCM unlocking and why do I need it?
PCM unlocking removes the factory security encryption on your vehicle's Powertrain Control Module, allowing tuning software like HP Tuners to read and write custom calibrations. Most 2015+ Dodge, Chrysler, Jeep, and RAM vehicles require this step before any custom tuning can be performed. N2 Speed offers same-day PCM unlock service with 1-day turnaround — just mail your PCM module to us.
How does remote tuning work?
You purchase an HP Tuners or DiabloSport device from us, read your vehicle's stock file, and email it to our team. We write a custom tune based on your mods, fuel type, and goals, then send it back for you to flash. We communicate in real time via email to fine-tune until it's perfect. No shop visit needed — everything is done remotely.
What vehicles do you tune?
We specialize in Dodge (Charger, Challenger, Durango), RAM 1500/2500/3500, Jeep (Grand Cherokee, Trackhawk, Wrangler), Chrysler 300, and GM platforms including C5/C6/C7 Corvette, Camaro, Silverado, and Sierra. Both naturally aspirated and forced induction setups.
Do I need to ship my car to you?
No. Our remote tuning service is done entirely through email and your tuning device. For PCM unlocking, you mail just the PCM module — not the vehicle. For tune files, everything is handled electronically. We serve customers nationwide.
What is the difference between Stage 1, Stage 2, and Stage 3 tunes?
Stage 1 is for stock or lightly modified vehicles. Stage 2 covers moderate bolt-on modifications like intakes, exhaust, and headers. Stage 3 is for heavily modified builds including cams, superchargers, turbo kits, or stroker engines. Each stage is custom-calibrated to your specific setup.
How much horsepower can I gain from a custom tune?
Gains depend on your vehicle and modifications. A stock 5.7L HEMI typically sees 15-30 HP from tuning alone. Modified vehicles with bolt-ons can see 30-60+ HP. Forced induction builds often gain 50-150+ HP with proper tuning and supporting mods.
Do you offer MDS delete tuning?
Yes. Our MDS delete tune disables the Multi-Displacement System on 5.7L and 6.4L HEMI engines, keeping all 8 cylinders active at all times. We also offer speed limiter removal as part of our custom remote tuning service.
Can you tune a C5 or C6 Corvette remotely?
Absolutely. We specialize in remote tuning for C5 Corvettes (LS1/LS6) and C6 Corvettes (LS2/LS3/LS7) using HP Tuners. If your ECM is locked (E90, E68, or E99), we offer mail-in ECM unlock service with fast turnaround.
What is ABS module programming?
ABS module programming is required when replacing or repairing the Anti-lock Braking System module on Dodge, Jeep, Ram, and Chrysler vehicles. N2 Speed provides remote ABS module programming service to ensure proper communication between the new module and your vehicle.
Is a custom tune safe for my engine?
Yes, when done by experienced tuners. Every N2 Speed tune is written conservatively with safe air/fuel ratios, timing, and operating parameters. We tune for both performance and longevity, and we monitor data logs to verify everything is within safe limits.
What tuning devices do you support?
We primarily work with HP Tuners (MPVI2/MPVI3) and DiabloSport (inTune i3, Trinity 2, Predator 2). We also support Pulsar modules for RAM trucks. The best device depends on your vehicle and tuning goals.
Can I return to stock after tuning?
Absolutely. Both HP Tuners and DiabloSport devices save your original stock file before flashing a custom tune. You can restore the factory calibration at any time with a few clicks.
Do you offer warranty on your tunes?
We stand behind every tune we write. If you add modifications or change your setup, we offer free or discounted re-tunes to match your new configuration. Our goal is a happy, repeat customer.
