6.7 POWERSTROKE DIESEL REPaIR & PERFORMaNCE

COMMON 6.7 POWERSTROKE ISSUES & DIaGNOSTICS
The Ford 6.7 Powerstroke is built for power, towing, and heavy-duty performance, but as mileage increases and workloads become more demanding, known problem areas begin to surface. At Southwest Auto, we specialize in diagnosing and repairing these issues with precision and clarity. Our team regularly addresses intercooler failures, boost leaks, cracked or failing cold-side charge pipes, and restrictive factory intake systems that limit performance. We also diagnose low-pressure fuel system concerns and the well-known risks associated with the CP4 fuel pump, which can lead to significant damage if not addressed early.
Our diagnostic process is thorough and built around identifying the root cause of the problem rather than guessing. If your truck is experiencing loss of power, poor fuel economy, or excessive smoke, we use advanced tools and proven testing methods to pinpoint exactly what is happening. Every recommendation is clearly explained so you understand what your truck needs and why. With over 37 years of experience and a commitment to honest, no-pressure service, we help Dallas Powerstroke owners avoid unnecessary repairs while ensuring long-term reliability. Our goal is to fix the issue correctly the first time so your truck performs the way it was designed to.
POWERSTROKE UPGRaDES & DIESEL SERVICE SOLUTIONS
Improving the reliability and performance of your 6.7 Powerstroke requires the right upgrades installed with purpose and experience. At Southwest Auto, we offer proven performance solutions that address factory limitations while enhancing drivability, towing capability, and efficiency. We install S and B oversized fuel tanks to extend driving range, high-performance air intake systems to improve airflow, and upgraded intercoolers with hot and cold side charge pipe kits to eliminate weak factory components. For fuel system reliability, we offer FASS fuel systems that improve filtration and delivery, as well as DCR fuel system conversions designed to eliminate common CP4 failure risks.
Every upgrade recommendation is tailored to how you actually use your truck. Whether you rely on your Powerstroke for daily driving, towing heavy loads, or demanding job site work, we build solutions that support your needs. In addition to performance upgrades, we provide complete diesel maintenance and repair services including engine diagnostics, fuel system service, preventative maintenance, and performance inspections. Our experienced diesel technicians focus on long-term reliability and consistent performance rather than quick fixes. Dallas truck owners choose Southwest Auto because we provide honest recommendations, dependable results, and service designed to keep your truck running stronger for the long haul.
