Stage 1 Tuning

Stage 1 is a bolt-on ECU tune that unlocks safe, reliable power gains without major hardware changes. Typical benefits:

  • Increased horsepower and torque across the rev range
  • Improved throttle response and smoother power delivery
  • Optimized fuel & ignition timing for efficiency and drivability
  • No engine disassembly — factory reliability retained when performed correctly

What’s included:

  • ECU remap calibrated to your vehicle and fuel
  • Supporting checks (boost, fueling, temps) and road/bench validation
  • Optional rollback to stock configuration

Optional Pop & Bang Package (additional cost)

  • Adds aggressive overrun/decel flame and crackle effects (“pop & bang”) via ignition and fueling strategies
  • Eye‑and‑ear‑catching sound for shows and street appeal
  • Available as an add-on during tuning; may increase exhaust wear, affect emissions compliance, and is not recommended for track or hard daily use

Contact us to schedule a Stage 1 tune and choose whether you want the Pop & Bang option.

Stage 2 Tuning

Stage 2 is an upgraded ECU/TCU tune paired with bolt‑on hardware for higher power and durability. Typical benefits:

  • Bigger horsepower and torque, especially mid/top end
  • Improved boost control and quicker spool
  • Better heat and fueling management for higher loads
  • Built for spirited driving and occasional track use

What’s included:

  • ECU/TCU calibration matched to your hardware and fuel
  • Checks for boost, fueling, temps and road/bench validation
  • Tuning for turbo/intake/exhaust/intercooler upgrades
  • Optional rollback to previous or stock tune

Optional Pop & Bang / Flame Package (additional cost)

  • Adds loud overrun crackles, backfires or occasional flames
  • Strong show effect; increases exhaust/turbo wear and may affect emissions/legal compliance
  • Available as an add‑on during Stage 2 tuning

Stage 3 Tuning - Custom Tunes

Stage 3 — Custom Tuning & Built Engines

Full custom ECU/TCU calibration for heavily modified or built engines. Designed for max power, durability, and track reliability.

Typical benefits:

  • Major horsepower and torque gains across the rev range
  • Precise boost, fuel, ignition and timing control for high horsepower setups
  • Engine and transmission safety strategies for sustained high-load use

What’s included:

  • Fully bespoke calibration matched to your exact hardware, fuel, and goals
  • Comprehensive system checks (boost, fuel system, temps, knock control) and dyno/road validation
  • Support for engine swaps, forged internals, big turbos, methanol/water systems, and transmission reinforcement
  • Optional rollback or conservative map for daily use

Optional Pop & Bang / Flame Package (additional cost)

  • Aggressive overrun/backfire or flame effects available as an add‑on; increases wear, may affect emissions/legal compliance, and is not recommended for reliability-critical or full-time track use
