NO CORPORATE LIMITS

Your MK8 Golf R or Audi S3 isn’t slow. Factory programming is holding it back. This iE tune safely reprograms the engine computer, stripping away those limits and replacing them with a new, unchained personality. Experience savage acceleration and custom-coded performance tech that makes your R / S3 unhinged when you want it, and civil when you don’t.

GAIN UP TO 132 HP

iE MK8 Golf R tuning delivers gains of up to 132 HP and 110 ft-lbs. Unlike inferior tunes, power builds cleanly and consistently without spikes, hesitation, or clunky behavior. Acceleration pulls hard, throttle response is exact, and driving behavior is perfected for everyday use. Sophisticated when cruising. Brutal when you floor it.

FULL POWER, NO EXCUSES

On many MK8 Golf Rs and S3s, the transmission computer is locked, forcing most tuners to reduce output or force “low-torque files” to ensure smooth shifts. iE wrote custom code to force the transmission to safely accept more torque from the engine side. This custom code bypasses torque limiters and safely increases hydraulic pressures to increase clutch capacity without a transmission tune. Full power, no compromises.

CUSTOMIZE YOUR SOUND

Turn on Exhaust Crackles to give your Golf R or Audi 8Y S3 attitude with dramatic pops and burbles on decel and shifts. Make instant changes from the app to turn it up, tone it down, or switch it off in real time. Kill the drone or free the beast by controlling your exhaust flaps from the app. The sound you want, exactly when you want it.

NEVER GET CAUGHT SPOOLING

iE Anti-Lag™ builds boost before you move, delivering hard-hitting AWD launches that grip and go. Rolling Anti-Lag™ (RAL) delivers the same advantage at speed for immediate power from a roll. Instant launch RPM adjustments from the app or your cruise control stalk keep you ready for any surface.

ADJUSTABLE THROTTLE RESPONSE

iE tunes come standard with predictable and proportional throttle response mapping. Or take command with 15 customizable settings ranging from calm and linear to sharp and immediate. Changes apply instantly in the app, so you can switch from economy to aggressive at any time. One tune, multiple personalities. No dangling hardware needed.

TRUEFLEX: E85 MADE EASY

Ethanol is like rocket fuel for your Golf R, but using it shouldn’t feel like a science project. iE TrueFlex™ adds real flex-fuel intelligence, reading ethanol content and instantly optimizing boost, timing, and power to safely deliver maximum performance for the exact fuel in your tank. No measurements. No math. No reflashing. Fill with 91/93 pump gas, full E85, or any blend in between. Just fill and drive.
