GTO 2004 LS1 | ID1300-XDS | Injector Dynamics | 1300.60.14.14.8
ID1300-XDS, for GTO 2004 / LS1 applications. 14mm (purple) adapters, set of 8
The ID1300 is an all new injector, designed in partnership with Bosch Motorsport. This collaboration has given us the ability to design a high flow injector with characteristics specific to the needs of the motorsport tuner. The ID1300 was designed with alternative fuels in mind, and is the only performance injector available with all stainless internals. It is compatible with all known fuels, and will stand up to the corrosive nature of alcohol better than any injector on the market.
While the ID1300 was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300 has a minimum fuel mass compatible with gasoline use, and will provide exceptional idle and cruise behavior under these conditions. In addition to its multi-fuel capabilities, the compact body of the ID1300 allows fitment in 200+ applications, making it the most versatile injector in our lineup. The 1300 has continued to be refined and improved over the years, and the 1300-XDS is the latest and best version to date.

Frequently Asked Questions About ID1300-XDS Injectors for GTO 2004 LS1
What maximum E85 horsepower will the ID1300-XDS set support on a turbo or supercharged 2004 GTO LS1?
The ID1300-XDS (1335 cc/min at 43.5 psi) is sized for high-flow LS V8 performance. This set of 8 supports forced induction E85 setups well into the 900 to 1050+ wheel horsepower range, offering maximum safety margin for all high-boost LS1 GTO builds.
Is the 60mm length of the 1300.60.14.14.8 injector a true drop-in replacement for the 2004 GTO LS1 factory fuel rail?
Yes, it is a direct fit. This ID1300-XDS set is configured to the standard 60mm O-ring to O-ring length required for the LS1. It installs directly into the factory fuel rail and manifold bosses without requiring spacers.
Does this USCAR ID1300-XDS set require PNP adapters to connect to the 2004 GTO LS1 factory harness?
Yes, adapters are required. The ID1300-XDS uses the modern USCAR connector. The factory 2004 GTO LS1 harness uses the older rectangular EV1 (Minitimer) connector. You will need eight USCAR to EV1 PNP adapters (ID P/N 90.1) for a clean, non-splicing electrical hookup.
Where can my tuner find the complete Injector Dynamics Dead Time data for the ID1300-XDS when tuning the GTO LS1 PCM with HP Tuners?
Injector Dynamics provides comprehensive characterization data, including Dead Time (Latency) and Flow vs. Pressure tables (based on ID1300x2) for the LS1 PCM. This data is mandatory for the ECU to precisely calculate the injector pulse width, which is critical for stable idle and smooth cruise with these high-flow injectors.
What common 2004 GTO issue can mimic a fuel injector problem or poor tune after installation?
A common 2004 GTO issue is the wiring harness wearing through the insulation near the glove box, or faulty front radius rod bushings that cause unstable handling. If misfires or rough running persist despite correct injector data, check the engine's physical health and wiring before further tuning changes.
