Expert Insight: More Than Just a Fix
We recently helped a contractor whose ’98 GMC Sierra 2500 was failing emissions tests and stalling at job sites. He had already replaced the spark plugs, wires, and multiple sensors with no luck. The issue was a failing processor within the original PCM. After installing our pre-programmed 1998-1999 Chevrolet 2500 PCM 16250279, his truck not only passed emissions with flying colors but he reported a noticeable improvement in low-end torque for towing. The updated software didn’t just fix the problemโit made his work truck work better.
