Our first 100% XDI manufactured and tested DI-Injectors are designed for the new GM LT series engines. With a 65% increase in flow over stock LT4 injectors, these supply the required fuel flow for high horsepower applications without the need for auxiliary fuel systems. These injectors are based on the original GM LT4 injector, which makes them a perfect drop in solution. Most of the ECU Injector characteristics stay the same.
Every Injector gets tested at 100bar and 200bar on OEM testing equipment at XDI. Every set gets flow matched to within ±0.5% at 100bar and 200bar fuel pressure !!!

Testing on several fully instrumented engines (8x O2, 8x EGT) done by Katech Inc. has shown unequaled results in terms of cylinder distribution, repeatability and stability at pressures up to 3000psi. Tuning changes required are minimal, offsets and current driver parameters stay the same. The injectors are E85 compatible.

no meth, no PFI, no extra ECUs, no wiring, full control, full OBD Diagnostics.
