The Ford Lightning has a lot of potential as well as its sister the Harley Davidson. The most common mods are a high flow air filter/intake and 4lb or 6lb lower pulley. This increases the boost from about 8psi to 12-14 psi. This will increase the power from about 345 rwhp to close to 400 rwhp with torque reaching as high as 500 rwtq. The 5.4L motor has the potential to make even bigger power but the stock rods are too weak. Are you running a “mail order tune” with higher boost? With the high cylinder pressures that comes with added boost it’s even more important to make sure your air/fuel and timing are safe. You can break these motors easily with a “bad” tune. We also offer a custom transmission tune that was designed after extensive testing on the street for maximum performance as well. It’s included in every custom tune.
When tuning we make sure your air/fuel is safe and you don’t have too much timing. SCT’s “canned” tune actually puts too much timing in this motor, especially when it’s cooler. We make the required changes in the tune to make sure the motor’s safe. We data log as many as 20 parameters while tuning to make sure everything’s safe and working properly.
