Why Louisiana customers mail in duramax lb7 / lly ficm repair

Louisiana has roughly 3.8 million registered vehicles, and full-size pickups & SUVs make up much of what New Orleans-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Louisiana — we see a steady stream out of New Orleans, Baton Rouge, Shreveport. Neighboring state — 1-2 days each way.

What we see from the South

Sustained underhood heat is the dominant stress on southern trucks, and heat is cumulative: it does not usually fail a board outright, it ages the joints and the power-supply components until a fault appears warm and disappears cold. If your truck starts fine at dawn and acts up at noon, say so when you ship — that pattern points somewhere specific on the board.

Louisiana FAQ

Common questions from customers shipping from Louisiana.

How long does shipping take from Louisiana to your Arlington TX workshop?
USPS Priority Mail from New Orleans, LA reaches our Arlington workshop in about 1-2 business days. USPS Priority is a short run southeast from the North Texas network; often 1-2 days. We start work the same day your module arrives and typically ship back next business day at the return speed you chose at checkout.
How much does it cost to ship a module from Louisiana?

The customer pays shipping to us; return shipping back to Louisiana is selected at checkout — $24.95 standard (3-5 business days), $54.95 UPS 2-Day, or $94.95 UPS Next Day Air, flat nationwide. Neighboring state — 1-2 days each way.
Do you accept duramax lb7 / lly ficm repair modules from Louisiana?
Yes — we receive modules from New Orleans, Baton Rouge, Shreveport, Lafayette and the rest of Louisiana regularly. With about 3.8 million registered vehicles statewide, full-size pickups & SUVs are the bulk of what we see from Louisiana.
Is there a duramax lb7 / lly ficm repair shop in New Orleans I should use instead?
Most New Orleans shops don't keep the bench equipment for duramax lb7 / lly ficm repair — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Neighboring state — 1-2 days each way.
Does Louisiana vehicle inspection or emissions testing affect this service?
Louisiana requires a safety inspection sticker statewide, with emissions testing in a handful of Baton Rouge-area parishes. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Louisiana and federal requirements.
Does my truck even have a separate FICM?
LB7 (2001-2004) and LLY (2004.5-2005) trucks do. From the LBZ onward GM moved the injector drivers inside the ECM, so those trucks do not have a separate FICM to repair — an injector-driver fault there is an ECM job. The 2006 model year is the one to be careful with, because early builds are LLY and later builds are LBZ. Send us your VIN and we will tell you which one you have.
Will I get my own module back?
Yes. This is a repair, not an exchange. Your module is opened, repaired and returned to you with its data and configuration intact, which is the main reason to repair rather than replace — there is nothing to reprogram because it is still the module your truck already knows.
