Unlocking the true potential of the TTS 8J requires a robust ignition system to match increased fuel and airflow. As you push higher boost pressures through the EA113 engine, factory ignition components can struggle to deliver a consistent spark. If you are looking for a massive power increase without a permanent ECU remap, we supply premium plug-and-play performance chips to safely manipulate sensor signals and unlock significant horsepower. To eliminate spark blowout under heavy load, upgrade to high-performance coil packs, which are a highly recommended reliability modification for any tuned 2.0 TFSI vehicle.
