Description

The GM Performance PCM-1005 is a programmed Engine Control Module (ECM) tailored for 2003-2007 LS and Vortec Gen 3 drive-by-wire engines. This module is essential for managing engine parameters like fuel and ignition timing, ensuring optimal performance and efficiency. This specific PCM requires the use of PSI harnesses and is programmed with the correct operating system for your engine and transmission combination. It is a key component for LS or Vortec engine swaps, particularly in older vehicles or custom builds where a standalone system is needed. The programming ensures the engine runs efficiently with the correct parameters for fuel, ignition, and other critical functions.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
