Frequently Asked Questions About the ID1750-XDS CTS-V 09+

What makes the ID1750-XDS a necessary upgrade for the supercharged CTS-V (LSA) engine?

The ID1750-XDS offers an extreme flow capacity of approximately 1728 cc/min at 3 Bar, which is essential for heavily modified LSA engines running high boost and making over 900+ horsepower, especially when using E85.

Does the ID1750-XDS for the CTS-V use the OEM EV6/EV14 electrical connector?

Yes, this specific ID1750-XDS set (Part No. 1750.34.14.15.8) features the USCAR (EV6/EV14) connector for a perfect, plug-and-play fit into the factory wiring harness of the 2009-up Cadillac CTS-V (LSA).

What is the minimum pulse width stability of these injectors and how does it affect the LSA?

The injectors have outstanding minimum pulse width stability, meaning they can precisely manage fuel delivery even when barely open. This is crucial for maintaining a smooth, reliable idle and excellent low-speed cruising in the high-horsepower LSA.

Are these Injector Dynamics units compatible with the existing LSA fuel rail and supercharger system?

Yes, this specific ID1750-XDS unit is engineered with the correct overall length and fittings to drop right into the factory or common aftermarket fuel rails used with the LSA supercharger manifold.

Is upgrading the fuel pump mandatory when installing ID1750-XDS injectors in the CTS-V?

Yes, it is highly recommended and usually mandatory. Due to the high flow requirement, the factory fuel pump assembly will likely be unable to maintain sufficient pressure, especially when running E85, necessitating a high-performance pump upgrade.
