We offer the definitive solution: a professionally programmed engine computer, ready to install and restore the reliable performance your GM vehicle is known for.

An Old Pro’s Tip: On these late-90s GM Vortec trucks, the PCM is the undisputed brain of the operation. It controls everything from the fuel injectors and spark timing to when your 4L60E or 4L80E transmission shifts. When we program your module with your VIN, we’re not just making it compatible; we’re ensuring it has the correct data for your specific axle ratio, tire size, and emissions equipment. This is the key to restoring that smooth, reliable power you depend on, whether you’re hauling tools to a job site or towing a trailer on the weekend.
Getting your vehicle back to factory-spec operation is simple. After your purchase, just provide us with your VIN, and our technicians will handle the programming. We’ll ship you a module that’s ready to be installed, allowing you to bypass dealership costs and delays. This is the straightforward, reliable fix for your 1998 Express 2500 PCM 16250279.
Frequently Asked Questions
Do I need to do anything after I install the PCM?

Instructions are readily available online for your specific model. Some vehicles may also require a Crankshaft Variation Relearn (CASE relearn), which requires a capable scan tool.
How do I provide my VIN number?
