Additional information
Frequently Asked QuestionsNo. The included Force Fuel Delivery system connects directly to your existing mechanical or low-pressure fuel pump. It uses an internal 340-LPH pump inside a 0.5-gallon reservoir to supply 58 PSI high-pressure fuel to the throttle body without requiring fuel tank modifications or new under-car supply lines. The FiTech 35271 ECM features an integrated electronic transmission controller designed specifically for popular GM automatic transmissions, including the 4L60E, 4L65E, and 4L80E. Shift points, shift firmness, and torque converter lockup can all be adjusted directly via the touchscreen handheld controller. This system is tailored for GM LS-series engines (such as LS1, LS2, LS3, LS6, and truck 4.8L/5.3L/6.0L variants) up to 650 HP in naturally aspirated applications. It features four flow-matched 80 lbs/hr injectors, a 950 CFM 4-barrel square-bore throttle body, and pre-terminated LS engine sensor connections. You must be logged in to post a review.
