Offering a 157hp increase at the tires over stock, the Edelbrock 158333 kit will unleash the max potential of your truck. Edelbrock’s engineers collaborated with Garrett on the design of all new turbos for the 3.5L EcoBoost trucks. These new direct bolt in turbos incorporate the latest in turbocharger technology offering a 54% increase in airflow over the factory turbos. A 60mm billet compressor wheel produces great improvements in compressor efficiency and flow. The 50mm Inconnel turbine wheel and larger .45 A/R stainless steel turbine housing result in a 52% increase in turbine flow. The 2.75” compressor inlets are 38% larger than the factory turbos complementing our high flow turbo inlet piping. The new turbochargers combined with our larger Intercooler, air inlet tubes, and high flow air filter offer huge increases in power potential for this application. To compliment the improvements in airflow, the Stage 3 kit includes an electronic booster for the fuel pump enhancing fuel delivery and unlocking even more power potential. A flashing device (tuner) is included for flashing the Edelbrock Stage 3 calibration into the trucks PCM. The included calibration is specifically engineered for the components included in this kit and takes advantage of this increased power potential while keeping this upgrade to your truck 50 state legal.
