Wake it up. Loud. Fast. Fun.

You didn’t buy a VR6 to drive like your grandma. Our Stage 1 ECU Tune is here to finally unlock that hidden power your MK4’s been begging for. No dealership tricks, no "just reset the ECU" crap. Just real gains, spicy sound, and that head-snap throttle you’ve always wanted.

Whether you’re hitting revs in a parking garage or gapping your buddy’s Altima, Boost Dynamic Tuning has your back with a plug-and-play tune that slaps.

Real Gains (Wheel HP/TQ):

• +10–20 WHP

• +10–20 WTQ
  (Yes, you’ll feel it.)

⚙️ What We Change (a.k.a. The Secret Sauce):

• Sharper throttle response

• Added fuel and ignition timing

• More aggressive cam timing

• Raised idle and speed limiter

• It revs harder. It moves faster. Period.

What You Get:

• No Lift to Shift (NLS) – stay in boost between gears

• Immobilizer Delete – swap ECUs, no drama

• Emissions systems OFF (for off-road use only):

  • EVAP

  • N80

  • Rear O2

  • SAI

Optional Fireworks:

• Crackle/Pop Options

  • Light (subtle but spicy)

  • Medium (daily-driven chaos)

  • INTENSE (?flames possible if straight piped)

• 2-Step / Anti-Lag / Launch Control

  • Avg. set to 4500 RPM

  • Manual trans only — autos, sorry you’re out.

Whether it’s your first mod or your tenth, this tune transforms your VR6 from “kinda quick” to certified menace.

So go ahead — make it bark, make it shoot flames, make it yours.
