For more information, visit IE Stage 1 C8 EA825 ECU calibration dramatically increases hidden performance with up to 828HP and 862ft-lbs! IE's advanced tuning platform releases hidden power, maximizes the drive feel, boost delivery, throttle response, and powerband to completely transform your 4.0TT engine into a supercar powerhouse. Engineered to operate on entirely stock hardware or with an upgraded intake and intercoolers for the most performance.
INCLUDED OCTANES
Your IE tune purchase includes multiple fuel options that offer dramatic power increases. Using your IE POWERlink, switch between octanes as often as you like allowing you to run 91/93 pump gas or flash to our race gas 104 or ethanol files for a massive increase in HP & TQ in only minutes.
FULL E85
Flashing the E85 fuel map allows easy fill-ups at the pump without mixing ethanol blends. This ethanol calibration delivers a massive increase in power over regular 91/93 pump gas while keeping mid-range power in check with the factory direct injection (DI) system and avoiding lean conditions, misfires, and power loss. E85 offers amazingly fast and consistent power delivery from the pump and is much less expensive than race gas.
E40 BLEND
Ready to experience an absolute torque monster!? Mixing regular 91/93 pump gas and E85 at a 40% ethanol content (E40) creates a blend that stays within the safe limit of fuel delivery for the factory injectors. This allows the E40 calibration to produce the full torque output available from the twin-turbo V8, resulting in an insane 862ft-lbs of torque that translates to a pull with seat slamming g-forces.
104 RACE GAS
In areas that do not have readily available ethanol or track enthusiasts with accessable race fuel pumps, the included 104-octane race gas file also succeeds in a considerable jump in power over regular pump gas. Sunoco GT260 Plus 104 octane is used to develop this tune and is highly recommended for the best results.
ADVANCED MAPPING
The factory ECU calibration is full of regulations and compromises that limits horsepower/torque and dull the power delivery and throttle feedback. IE calibrators re-tuned the complicated mass flow modeled boost control mapping with advanced strategies to achieve precision boost request targeting that results in unmatched power delivery. The throttle mapping also receives a significant rewrite to deliver a linear and predictable throttle feedback. These refinements result from months and months of fine details that dramatically improves your conneciton to the car with a much sportier and precise feel.
BRAKE BOOST
Commonly used in roll racing, Brake Boosting allows you to build extra turbo boost by applying brake pressure while accelerating. Release the brake pressure for a "rolling launch" and leg up on the competition.
EGT OPTIMIZATION
Exhaust Gas Temperature (EGT) is the measurement of fuel mixtures exiting the exhaust and is used to determine the health of the fuel/air mixture entering the engine. IE engineers have spent countless hours adjusting boost air/fuel ratio, ignition timing angle, camshaft phasing, intake air temps, and much more to develop the proper EGT adjustments for ultimate engine safety without sacrificing power on all octanes.
