Diesel owners love their engines for torque, durability, and efficiency. But sometimes stock isn’t enough. At Rob’s Automotive Repair Center in Clackamas, OR, we provide diesel performance tuning and upgrades that add safe, usable power while protecting reliability. Whether you want stronger towing performance, better fuel economy, or carefully selected upgrades, our technicians can help you get the most out of your diesel.

Why Consider Diesel Performance Upgrades?

Performance tuning and upgrades can:

• Increase horsepower and torque for towing or hauling
• Improve fuel efficiency with optimized programming
• Extend engine and transmission life with supporting upgrades
• Enhance driveability and throttle response
• Provide reliability-focused modifications that prevent known issues

The goal isn’t just more power—it’s power you can depend on.

Diesel ECU Tuning & Programmers

Modern diesels rely heavily on computer controls. With the right tuning, you can unlock significant improvements. We offer:

• Performance programmers & tuners (for Cummins, Power Stroke, Duramax, and European diesels)
• Custom tunes optimized for towing, economy, or balanced daily driving
• Relearns & calibration updates for reliability and smooth operation

We tune responsibly—keeping your diesel compliant while giving you the performance you’re looking for.
