Why Montana customers mail in duramax lb7 / lly ficm repair

Montana has roughly 1.7 million registered vehicles, and full-size pickups & 4x4 SUVs make up much of what Billings-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across Montana — we see a steady stream out of Billings, Missoula, Great 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.

Do you accept duramax lb7 / lly ficm repair modules from Montana?
Yes — we receive modules from Billings, Missoula, Great Falls, Bozeman and the rest of Montana regularly. With about 1.7 million registered vehicles statewide, full-size pickups & 4x4 SUVs are the bulk of what we see from Montana.
Is there a duramax lb7 / lly ficm repair shop in Billings I should use instead?
Most Billings 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 Montana vehicle inspection or emissions testing affect this service?
Montana has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Montana and federal requirements.
What if my module cannot be repaired?
We inspect and test before we do any repair work. If the board is beyond economical recovery — severe liquid damage, extensive corrosion, or damage to areas that cannot be reliably rebuilt — we stop, tell you what we found, and you are not charged for a repair we cannot deliver. You get the module back if you want it.
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.
