MapEV Performance Tuning (Porsche Taycan & Audi E-tron) from EFI Motorsport

EFI Motorsport is a company dedicated to providing quality upgrade parts, hardware, software, and service for a range of European vehicles.

If you're looking to unlock the true potential of your electric Porsche or Audi, MapEV's performance tune is one of the most dramatic upgrades available on the market today. MapEV replaces your vehicle's powertrain control software with a custom-optimized tune that dramatically increases horsepower and torque, sharpens throttle response, and unlocks launch mode for everyday driving — not just track conditions. To put the numbers in perspective: a 2025 Porsche Taycan 4 with the performance battery goes from the factory's 435 PS (430 HP) all the way up to 940 PS (927 HP). That's more than double the stock output, on a street car.

Gains vary by model, but every variant in the Taycan and e-tron GT / RS lineup is supported. This is a plug-and-play replacement module — your original, unmodified controller is kept completely intact and can be reinstalled at any time. Heading to the dealership? Simply swap it back in. No one will ever know.

Compatible with J1.1 for 2020 through early 2024 models, and J1.2 for late 2024 facelift models and newer.

Please note: A valid VIN is required at the time of purchase and orders will be held until one is provided. Your vehicle must also be identified through MapEV's diagnostic software before a flashed controller can be shipped, ensuring your tune is built specifically for your car.
