Why Colorado customers mail in duramax lb7 / lly ficm repair

Colorado has roughly 5.3 million registered vehicles, and trucks & 4x4 SUVs make up much of what Denver-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Colorado — we see a steady stream out of Denver, Colorado Springs, Aurora. Regional west — about 2 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.

Colorado FAQ

Common questions from customers shipping from Colorado.

How long does shipping take from Colorado to your Arlington TX workshop?
USPS Priority Mail from Denver, CO reaches our Arlington workshop in about 2 business days. USPS Priority runs northwest from the North Texas network; roughly 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.

Do you accept duramax lb7 / lly ficm repair modules from Colorado?
Yes — we receive modules from Denver, Colorado Springs, Aurora, Fort Collins and the rest of Colorado regularly. With about 5.3 million registered vehicles statewide, trucks & 4x4 SUVs are the bulk of what we see from Colorado.
Is there a duramax lb7 / lly ficm repair shop in Denver I should use instead?
Most Denver 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. Regional west — about 2 days each way.
Does Colorado vehicle inspection or emissions testing affect this service?
Colorado requires emissions testing in the Denver-Boulder Front Range metro region; rural counties are exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Colorado and federal requirements.
Do you do DPF, EGR or DEF deletes while it is on the bench?
No. We do not offer emissions deletes or defeats of any kind on any platform, and we will not modify a module to disable emissions equipment. This service repairs the hardware failure that stops your truck running properly; it does not change what the truck is certified to do.
Do I need to send the ECM too?
Not for this service. Send the FICM by itself. If your symptoms or codes suggest the ECM is also involved we will tell you after testing rather than asking you to ship extra hardware speculatively.
