Frequently Asked Questions

FiTech PN 75211 is engineered specifically for cathedral port GM LS cylinder heads. This includes popular applications such as LS1, LS2, LS6, LR4, LM7, LQ4, and LQ9 engines. It is not compatible with rectangular port (LS3/L92) or square port (LS7) heads.

The Force Fuel system mounts conveniently under the hood and utilizes your vehicle's original mechanical or low-pressure electric fuel pump to feed its internal 0.5-gallon reservoir. An internal high-pressure pump submerged in fuel feeds the EFI system at a steady 58 PSI, eliminating the need to modify your factory fuel tank or run new fuel return lines to the back of the car.

No, laptop tuning is not required. The FiTech Ultimate LS system features advanced self-learning technology. After entering basic engine parameters via the supplied handheld color touchscreen controller, the ECU automatically optimizes air-fuel ratios and timing as you drive.
