Warning: My 'good enough' injector cleaning routine was costing me power

Honestly, I was just doing a quick spray with carb cleaner for years. After a full ultrasonic clean on a 6.7 Powerstroke, the difference in idle smoothness after just one week was night and day. Anyone have a better method they swear by for these newer high-pressure units?

Wait, you were just spraying carb cleaner on a 6.7 for years? That's wild, I thought everyone knew that wouldn't cut it!

My buddy's 6.7 in Bakersfield looked like a science project, @verab76.

Carb cleaner just moves the gunk around. I switched to a dedicated diesel intake cleaner and it made a real difference. The right solvent for the job matters.
