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.
