Why Idaho customers mail in duramax lb7 / lly ficm repair

Idaho has roughly 1.9 million registered vehicles, and full-size pickups & 4x4 SUVs make up much of what Boise-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Idaho — we see a steady stream out of Boise, Nampa, Idaho Falls. Cross-country northwest — about 3 days each way.

What we see from the West

Western trucks split into two duty cycles we see constantly: high-altitude towing and oilfield or ranch service with heavy idle hours. Both load the injector-drive side of the system harder than commuting does. Elevation itself does not damage a module, but the sustained high-load fuelling that comes with mountain grades and heavy trailers is real service life on the drivers.

How long does shipping take from Idaho to your Arlington TX workshop?
USPS Priority Mail from Boise, ID reaches our Arlington workshop in about 3 business days. USPS Priority routes northwest through the Mountain network; about 3 days given the distance. We start work the same day your module arrives and typically ship back next business day at the return speed you chose at checkout.

Do you accept duramax lb7 / lly ficm repair modules from Idaho?
Yes — we receive modules from Boise, Nampa, Idaho Falls, Coeur d'Alene and the rest of Idaho regularly. With about 1.9 million registered vehicles statewide, full-size pickups & 4x4 SUVs are the bulk of what we see from Idaho.
Is there a duramax lb7 / lly ficm repair shop in Boise I should use instead?
Most Boise 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. Cross-country northwest — about 3 days each way.
Does Idaho vehicle inspection or emissions testing affect this service?
Idaho requires emissions testing only in the Treasure Valley (Ada and Canyon counties); the rest of the state is exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Idaho 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.
