We’re excited to announce our Engine Control Unit (ECU) Upgrades are now available for the MK6 Jetta with the 1.4T engine! Expect great gains with 173-188 HP and 255-268 FT-LBS of torque on tap, depending on octane, from this simple software upgrade. Best of all, the upgrade flashes to the factory ECU via the vehicle’s OBD II port so there’s no ECU removal or physical modification necessary! Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!v
